Heart of the Alien (Sega CD) Playthrough

- A playthrough of Virgin's 1994 action-platformer for the Sega CD, Heart of the Alien: Out of this World Parts I and II.
This video shows a continuous run through both games. Heart of the Alien begins at 21:01.
Heart of the Alien is the sequel to Eric Chahi's Another World, a 1991 Amiga hit that was released in North America in 1992 as Out of this World on computers, the Sega Genesis, the Super Nintendo ( • Out of this World (SNE... ).
Interplay, the publisher of the console ports of Out of this World, had forged an agreement to produce a CD-based follow-up, and so Heart of the Alien came to be. The game landed on North American store shelves in the summer of 1994 as a Sega CD exclusive, and it remains one to this day.
The sequel is posed as direct continuation of Out of this World, so the disc bundles Heart of the Alien with an enhanced port of the first game. The extended ending from the 3DO version of OotW has been repurposed as HotA's intro sequence and serves as a bridge between the two games. (If you play OotW first, the game will continue directly into HoTA, just like Ys Books I & II did • Ys Book I & II (TurboG... ).
This version of Out of this World is a nice upgrade over the cartridge versions. Most of the slowdown has been eliminated, the animation is more fluid, the controls are snappier, and the sound quality has been improved. The speed in particular makes a huge difference. I never realized how slow the SNES game was until I played it on the Sega CD! The playthrough of the SNES version that I linked runs thirty minutes, and it took me just twenty minutes to get to there in this video.
Heart of the Alien initially feels a lot like the first game: it's a cutscene-laden, flip-screen platformer that demands memorization and pixel-perfect execution. This time, however, you play as Buddy, the friendly marshmallow dude who worked with Lester in OotW. Buddy is huge and wields an electric whip instead of a Light Phaser, but mechanically, the games feel very similar.
The art design, the flow of the action, the level design, and the storytelling are a wholly different matter. HotA prioritizes combat over puzzles, and it ditches OotW's atmosphere and environmental storytelling for a more bombastic, spectacle-laden approach.
Even though he originally gave the project his blessing, Eric Chahi blasted the quality of the final product and distanced himself from it in the media. On his website, he says that "[HotA's] concept was good but, alas, neither the animations nor the game, entirely developed by Interplay, were up to the job." Ouch. I can't say as I blame him, though. I didn't much care for the changes, either. I mean, I enjoyed it, and I think it's an alright game on its own, but it lacks OotW's special sauce.
The art is nice and the graphics are technically better, but it looks like they went with rotoscoped pixel art (and in some instances, FMV sequences) instead of vector graphics to render the characters and cutscenes. The animation is silky smooth and there's a lot more detail, but I can't help but feel that it looks cheap and cheesy in comparison. So much of it looks plain silly.
The gameplay feels like a second-rate imitation, too. Jumping is awkward and glitchy, the collision detection is frustratingly inconsistent, and most of the game's challenge stems from having to memorize which insta-kill trap lies just a few pixels from the edge of the next screen. And the story - what little there is - culminates in Interplay giving Lester the Tasha Yar treatment. All for the sake of cartoony spectacle, I suppose. What a shame.
Like I said before, it's an okay game, but I wouldn't call it a worthy successor to Out of this World. At least the inclusion of OotW makes the disc still worth owning.

NintendoComplete (www.nintendocom...) punches you in the face with in-depth reviews, screenshot archives, and music from classic 8-bit NES games!
one of the best games., no tutorial, no talking, no health bar, no UI, no timer,
you just play it and figure it out
awesome!
Thanks! :)
Exactly! took me like 3 hours to figure out the very first part with black lion thing chasing you! lo1
The original name of this game is "Another World". I used to play it a lot when I was a kid. Old schoolers like me know this game.
In North America it was released under the name Out Of This World so the name depends on your location. Not sure why they would change there name here but whatever it's still a good game.
@@Teh-Gaz from Wikipedia (but I heard the same story in a video here on youtube ;) ):
"The game was published in North America under the title Out of This World in order to avoid confusion with the popular but unrelated soap opera television series Another World."
this thing is in fact Another World/ Out of this world Parts 1 and 2 which means it carries on after where the original would end ... If you were able to finish it, that is ...
I was gonna say it was named something else when I played it but I found what it was called thanks this game is dope
@@Teh-Gaz The creator of the original game is for Amiga and the title is "Another World"
that game was ahead of its time.
way ahead, bro
I played Another World on my 386 way back when, what a game. And amazing sound out of the PC speaker as I had no soundcard.
The title for the Amiga500 was "Another world" .
@@paulmichaelfreedman8334 your right I remember.
I mean it's still a really intense good game.
This game was way ahead of its time! A masterpiece
Yesssss
So glad I could watch this just to get the story. I couldn't get too far myself as a kid. (Flashback was more my speed!) I always loved this game, but was never any good at it. Thanks for uploading this - brings me back
What the heck? I never knew the second "half" existed! I played Out of this World on PC/DOS, took me a long time to beat it without any clues, the flying at the end, that was it... but apparently not! Mind blown!!!
I even remember the "save" code for getting to that part where the guy rolls through the narrow pipe with the gas - CLLD
Man, the nostalgia is flowing. Such an underrated game.
The second half was Heart of the Alien, which was released a few years later than the original exclusively on Sega CD (you probably already knew that, apologies if so).
One code that always stuck in my mind to this day is XDDJ I think. I believe it puts you in the cave area. Beat both games! Such an awesome story told, considering no talking was ever done. Never did understand why they put the first one on the SNES where I played it, to the Sega CD, but I'm glad I had both of those at the time.😁
Heart of the Alien is also non-canon according to Eric Chahi, the original game's creator, since it wasn't made with him. Given how the game ends, yeah I think I get why he doesn't like the more..."definitive" end to be that.
This game was too hard for me when I was little kid. Actually never passed the beast scene. But imprinted in my core memory.
same here. and now i can't seem to find it anywhere! I have Out of this World on steam, but i want to play heart of the alien again!
Bro I was gonna leave the same comment. Im 45 now and just like u said I think as far as I got was pickin up the pistol from what i can remember. Im pretty sure I had this game on the commodore 64
Same here
Was WAY too hard. Watching this walkthrough, I can see why i couldn't get far. Some of the things you have to do are nonsensical. Still, a cool game, and I enjoy watching it more than playing when someone else knows what to do.
это была суперская игра
a masterpiece. Without this game we wouldn't had heart of darkness and oddworld, two other masterpiece.
I never even knew there was a second part! Played the PC version called "Another world" which ended with a dragon scene and ending credits, loved every minute of it but never knew about the sequel until today!
Same!
Same
Same
I remember being nine years old struggling to figure out this damn game.This and flashback” were the hardest games I’ve ever played
man this brings back HELLA memories. I played it on SNES, and I played it a whole lot. Finally beat it, it's such a fun game. I didn't even know part 2 existed until decades later, and this is the first time I'm watching a playthru of it
Friend of mine had this game for quite a while when we were kids. He told me that it only had one level - the encounter with the beast. The moment we played it together and i catched liana and ran to the other side was complete mindblowing for us... hahahah. Then we met like every afternoon to beat the game. Good times. Thanks for the video.
... IT HAS BEEN THIRTY YEARS AND I JUST LEARNED I CAN KILL THE WORMS?!
How did you get past 'em without?
Yeah, with a kick
@johnnybravo9096 By jumping like a mad man & getting lucky. This is so much easier, I had no clue about the kicking worms either 🤬
@@scottdecowski4913Man, that must've been frustrating af
@NintendoComplete I was playing on emulators so it wasn't too bad with saving but now I got a physical copy on Sega CD & it's impossible to pass without kicking 😅 glad I found this!
Use to play Out of This World and especially Flash Back on my Sega MD back in the 90's. One of the best memories of my youth.
I played the Mac version - called Out of this World - on my school's Mac LC 575s, and eventually my own 5260/100. This was around 1996. This game was so incredibly hard but so much fun and the graphics were stunning for their day.
The backgrounds are still noteworthy today. They still look amazing and prove that there's a difference between graphical fidelity and pure artistic beauty.
I player this game when i was child, but the name was "Another World".
so you must remember FLASHBACK - another good game from that times! 😊
Another world. Das war damals der Hammer! Da musste jeder Schritt sitzen.
Loved playing this game at my friends house when I was in high school.
My dad actually owns this on the Apple II. I got a chance to sit down and play some of it on the actual machine. Magical.
The astonishing drop in quality in heart of the alien is something else. Another world had something special going for it. A pure horror sci-fi adventure. Heart of the alien feels like a cheap imitation.
It is incredible what 16 colors may convey when well used
The sega cd could show up to 64 Color’s at once I believe and more with the “dithering” method on older televisions.
@@decoren45 absolutely, but for this game, they restricted the background color usage to 16 colors, which is the largest color count a megadrive/cd background plane tile may use, allowing also the vectorial videos to display faster
16 well-chosen colors, not the garbage RGB primaries. There's computer art from 1986 that still holds up because the Amiga had a high-resolution mode with 16 paletted colors.
No surprise the art for this was developed on the Amiga.
the visuals in this game are a masterpiece and it astounds me it came out decades ago with such rudimentary technology
Wtf?! How did I not know there was a part 2 this whole time?! I loved the first one. I played the SNES version "Out Of This World"
That beginning sequence takes a lot of trial and error to get through. Finally getting the gun gave a real sense of accoplishment
it was called “another world” on the pc but it was only the first half. never knew this sequel existed. thanks for the upload!
They released this game as Out Of This World in North America.
Another World is the european-ish name, no matter the support.
@@V3nom7 yes, i probably played the UK version
The second game I think was exclusively for the Sega CD, and is treated as non-canon, which explains why barely any know of it.
Man I loved the high quality audio of Sega CD. In that era of gaming it did make a difference
Yes and no. Sometimes sega chose the music well. sometimes... they did not.
TLDR - jump to @21:30 and watch a couple minutes to have your mind blown.
Deserves an award for the ambitious style, animations, and implementation of functionality given the hardware limitations at the time. Damn!
what was the mind blown? I'm only seeing the start of the sequel?
This is cool. A bit sad this was not included in the 20th anniversary release of Another World but also understand why. Thanks for uploading. Actually totally forgot it existed until now
I miss the good old days when you could run your particle accelerator at any time of the night when you couldn't sleep.
Ohh man I loved another world as a kid..I might even play it again now
I remember when this game came out on PC and was called Another World. It literally changed gaming as we knew it back in the day. Had no idea they ported this to Sega CD. Was so incredibly tough to beat!
the amiga game ended at 20:26. for many years I wondered what became of orange guy, about big guy and his imprisoned people.
finally I know. thank you random upload for this closure. for tying up the loose ends in my speculation. it ended the way it had too.
wow this was awesome to watch
I remember playing this game on the PC way back in the day when i was a kid and being absolutely blown away how stunning it looked. Never did get that far on it though because it was brick hard lol.
Haha...back in middle school...my PC had a 20mb hard disk...and this was one of the games that really made an impression on me...now that I'm in my mid 40's and looking at this...I have mixed feelings :)
I can't believe they made this game fit within 20mb! That just shows the skill level of the developers that made this game, and a masterpiece of its time at that. I loved this game too, but I really sucked at it..
This game blew me away when i was a kid whem i forst played it on the amiga.
I found it very hard ,never finished it,just kept replaying the same bits over and over.
Flashback was also very good,same style of graphics and gameplay.
Flashback was inspired by this game (both owned by Delphine Software), but without the participation of Eric Chahi.
i play flashback on a phisics teacher PC after scool when we clean up the rooms... And director of a scool catch me and on another day i have conversation with teachers ^) it was in 1994-1996 can't forget this situation, but from that days still keep playing games... 😁
I played this on PC and will never forget the cinematics, I was so blown away. This stuff is nothing new now, but back them, WOW!
One of the best...games...ever. With so many different names. =b
Very interesting. This is the first time I’ve seen gameplay of the sequel. It looks like it plays more like Dragon’s Lair (arcade).. love how buddy goes postal lol!
The game was very hard, but the music was amazing!
Love this game so much
For me as a kid the graphics were awsome, but today it is Rotoscope artwork! Honestly I never heard of the second part before. Maybe because it was sega cd "exclusive". I always thought 'Flashback' was the sequel.
I had no idea this game existed until now, pretty interesting. And wow what an unceremonious end for our protagonist. Pretty forward thinking to center the natives.
Played this 30 ish years ago on my Amiga.. Nothing was like it. And will never be...
I think my life would’ve gone differently if I had known about this game when it came out.
In Ireland, this game was released as Conan O'Brien's No Good Very Bad Day
Esse jogo estava muito a frente do seu tempo. Incrível. Nuca esqueci, desde criança. Fiquei fascinado por esse jogo.
I didn't even know there was a sequel to "Out of this World" and that it was only on a disc called "Heart of the Alien" for Sega CD lol.
This game's mechanics are so ahead of its time.
This game was brilliant. I think games were better back then. They were more creative and more challenging.
Ah, it is "Another World".
I recognized the Interplay graphical style, same as Flashback, I hoped it was a different game that I miss, I'm a bit disappointed...
Neverteless, it's always a pleasure to see this game, regardless of its title.
The biggest issue I have with this game is the obtuse "what the heck am I supposed to do" style of gameplay and "puzzles" that are very trial and error until you solve them almost by accident. The visuals are a marvel of its time, it was a delight to see rotoscopy used this early with this level of cinematography.
agreed. it's nearly a 2D "dragon's lair". I love the aesthetics though, and wish somebody would do a remake of at least the first one, more along the lines of a lucasfilm adventure game.
100%!!
Otherwise you could finish it the same afternoon you bought it.
@@ofonruiz I understand why they made it like that in that period of time, just stating that it's an extremely outdated gameplay design and a way of artificially inflating difficulty for that purpose. But it is what it is.
Dark souls of its day lol
I ended Another World in DOS in the 90s, I didn't know there was a sequel!! What a sad ending but, anyway, I always thought that he would never come back to his lab... beacuse there is absolutely no way.
The sequel is called flash back
@@crow4936 no its not
@@crow4936of course, it is not, Flashback is a totally different game, I was told when I was younger it is Another World sequel, but it was not, you little liar 😂
@@olafjurgiewicz624 at the time that's what the creator stated in an Amiga magazine interview they changed their tune years later.
i think he means everything after "the end" at 20:26 or abouts.
the rest of it is missing from many versions of the game.
Something about this game looks very modern. It looks like one of those good rare shelf games that was purposely pixelated that you would see on PS Vita, PS4|PS5, Nintendo Switch & Steam.
That's because it is , flash back was the original sequel to another world, this came out a few years ago.
the cutscenes were done with vector graphics and fills. not all that different from flash animations when it comes down to it, except done by hand in a more grueling manner. similar technology for a similar look.
@@crow4936 Flashback and Another World have no relation. Flashback was simply inspired by Another World, without the partiucipation of Eric Chahi, mainly because they were both owned by Delphine Software.
@@tsm688 Another World is not only vector, it's also using rotoscoping, the same technic you can see in the 1981 movie Metal Hurlant, or the recent clip "CRYSTAL THRONE - Mechanical Tyranny".
@@crow4936 Not only do I remember this game being released on Sega CD in 1994, but also any tiny research would show how your insisting of how Flashback was a cannon sequel to Another World is false.. I do remember people saying Flashback was the successor to Another World but only in the fact that it was a similar genre.. Its not even developed by the same developer.. The only link between the two games is that they are similar in presentation and that the developers are French. Can you provide any citation that Heart of the Alien is a modern title?
What's most amazing, I think, is that the SNES could still play this, at this same speed, without a CD add-on. However, the music on this is phenomenal though! I never heard such on the SNES cart.
This game is a peace of art!
Flashback (SEGA) is still one of my fav games of all time - so naturally I played Out of this World (SNES) too as a kid. I love them both to this day and will play them every few years. Heart of the Alien was very difficult for me so I didn't play it as much..
I remember watching my brother and uncle play this game on Super Nintendo. They beat the game eventually. I was 12 when it was released.
You didn't see them play this on a SNES, though. It was a Sega CD exclusive.
@@cigoLxeL No, Heart of the Alien was a Sega CD exclusive. Out of This World was ported to many different systems - including the Super Nintendo.
@@cigoLxeL oh I’m sorry I meant out of this world not heart of the alien.
Damn. That brings me back. I mean Holy shit I actually went to toys r us as a kid and bought this game with my allowance on release.
I completed Another world on my Amiga when I was nine/ten years old, I was so proud of myself lol, took me about a year and half a note pad..
That’s awesome!👏🏼 It was so rewarding back in those days when you finally got everything figured out and you beat it. This game was so ahead of its time.
@@ScentlessSun yeah it was man, classic on release
GGWP
Never knew there was a sequel (with a sad ending)!
You can tell (or hear) the audio was clearly SegaCD'ed!
what a bizarre game
the sound design is amazing
1994? wow these developers were thinking well outside any box at the time.
It's incredible what he did. The programming was made by one man, as far as I remember. It was not possible to load these graphics using the common techniques of those times, so the developer figured out his own way to do it. It's all documented, but incredibly complicated. I think there are documentaries on TH-cam, or somewhere on the web.
@@DiegoSynth Not complicated, but quite tedious : Chahi used rotoscoping for cutscenes, and vector for the rendering of the main gameplay. It's simple but very long to do, especially alone. He did it, and his friend composed the music.
This game set the bar so high
It was magnificent
Nothing came close at the time
このゲーム、取扱説明書も何も無しで クリアするのに5年以上掛かりました。
でも、非常に面白いゲームでした😊
Wow, I had no idea this existed!
I played tbis on Amiga, a computer that this game was designed for. It was jawdropping at that time
30 years later I know OFTW had a sequel... WHAAAAT !!!
And what an horrible ending.
Heart of the Alien is a bit subpar as a sequel, but the updated port of Out of this World that they included on the disc makes it worth having in your collection.
The gaming staff intended to leave the original as open ended. They had no desire to make a sequel and were pressured to make it happen by the game's massive success. That would explain the dissapointing end for our main protagonist.
nah , people did not like it since :
1. The human played dies ...
2. it was a SEGA CD EXCLUSIVE !!! To lure people to BUY THE SEGA CD !!!
That's it ... played it few years back and it was good ... people on the Amiga Side craved for this Sequel , when the news hit some where like in Cope mode ... making excuses that FLashBack is Another World 2
By the way the Amiga Version of this game called Another World has the 15:42 section removed ... the level ends on 15:23 and they go straight into the Alien Tank section ...
@@hfricIn the mid-90s as a teenager, I convinced my parents to let me rent a Sega CD from our local rental store just so I could play this and I hated it for neither of those reasons.
@@bigduke5902 "convinced my parents" "to rent a Sega CD" ok
@@hfric Lol what?
I finished OoTW after many frustrating defeats. You make it look so easy!
I learned about HotA by chance, much later, and since I loved the first one, I was very enthusiastic about it. Too bad it fell a bit short of its promise, and I feel that the ending was rushed somehow.
Need to play that. Only complete part 1 and flashback. The atmsophere in here is so damn good.❤
I would have never imagined the ending would go like that.
I know Red had no chances of survival anyway given is a alien world and even just breathing was a miracle, but him helping in toppling the slaver empire and then just dying and being ultra cremated, an it was in asequel, damn.
more effort than necessary when any average handgun could do the same thing LOL
And then put on display in the middle of town!
Tourism will skyrocket!
I thought the ending was pretty fitting and perhaps realistic, I mean no way he was ever gonna see home again.
@@mr.hatman9345 True. This is not the typical power fantasy. This is 'how long can we survive'.
The game's creator wasn't involved in the sequel, so he treats said game as non-canon. So as far as he's concerned, Lester's story ended with him just being exhausted in the first ending instead of straight up dying like a chump.
Looks just like out of this world part 1
Another World was one of only a handful of games I have ever bothered / been able to complete.
I had this on the amiga it was called Another World, which is also what it's called on the Google play store too for those wanting to relive their childhood
Another World!! :D
Wait... "Another World", "Out of this World" *and* "Heart of the Alien"? Starting to think this game has more names than that now.
I didn't know the game had a sequel.
Flash back was the sequel , this is modern.
@@crow4936 Incorrect. Flashback was a different franchise.
@@RyloreVanguard bullfrog said flashback was the sequel to another world when it came out in the 90s , bro I had Amiga and I got it when it came out.
@@crow4936 Flashback was a different franchise. You played as Conrad, not Lester, Flashback also had a sequel of its own called Fade to Black.
"the end" at 20:30 is where many versions of the game, well, ended.
Another World, phenomenal game for its time. Still impresses, even to this day.
Played this on 3DS- great game, but it took me a lot longer than 39 minutes to finish it!!
"heart of the alien" is "out of this world" and "another world", didn't know that. The ambiance is great until level 1, then you feel like in the jungle. Haven't watched the whole vid. Eric Chahi is Legendary. This game was unique in its era. And "From Dust" is remarkable. Not like all those repetitive games returning on each console. This is Art.
Somehow realistic for its' time. Reminds me Gandahar.
Man, this game and Zillion….FML.
this looks awesome
When I was little this game was right of passage, my dad used it as a test, it came with a paper decoder wheel and a code you had to crack, He said if you can solve it you can play it. Good times. Dad never got part 2, by then we had moved on to Fallout, and Crusader No Remorse.
The death scene at 30:14 is so unintentionally hilarious. It's like he's doing samba.
Never heard of this title, another world I played on the amiga in Uk. Great game.
All that running to end up in a furnace 😂
No joke, this feels like a modern indie game. Wild.
This is definitely a strange beast. It's not just a sequel but a midquel too. It didn't do a bad job of replicating the original's gameplay and art style though. A thing surprisingly many sequels "Video Game or Otherwise" couldn't even be bloody arsed to do.
I got to the very last scene, crawling to the control panel as a kid on the snes and never did beat it. Ugggh!
This version has ONE thing that's missing fron recent re-releases of Another World (Out if this World). That amazing soundtrack (from the original composer).
Because outside of the intro and ending, the original version of the game had no music.
@@POLE7645 I totally agree with you about the soundtrack. I got that re-release on the Wii U of all places and I was surprised to find it missing. I fell in love with this game on the SNES, but in my memory this versions score was always a part of it. It didn't occur to me so many years later they were so different.
Дизайн, режиссура, атмосфера- всё на достаточно высоком уровне
When I played this game all those years ago, it was called "Out of this World"
This (i know it as another world) and Flashback OMG this was good times. I wish i could turn back time.
Para mi, uno de los mejores videojuegos de todos los tiempos...
Played it on the Amiga 500 back in the days 😊
Would love a remake of this game with smoother animations.
There is. Came out some years ago
The 20 years anniversary edition for the First part Another World, released in 2013 on PC and some consoles.
This was really the first game to introduce this sort of story telling where little or no exposition is given to the player. Half Life had a very similar vibe, and I like to believe that Valve got inspired by Another World when making it.
I remember giving up on the 1st level after stepping on the poisonous slugs and being chased by the shadow mountain lion. I kept dying, I said f*k it! Glad to see how it plays out finally 34 years later 🤣
The Original game is Another World, the sequel is Heart of the Alien. SEGA packaged both games together and just called it Heart of the Alien.
Thanks. I thought that second part may have been fan made
ive always known this as 'another world' ....... one of my greatest gaming memories...... blew my head off as a kid, still looks amazing
