The Hole of Inferno mode can only be unlocked after you beat the normal route and Omake route can only be unlocked after beating the hard route. The last mission in omake route unlocks after you beat The Hole of Inferno mode.
The Hole of Inferno
A boss rush that pits you against Dark versions of 5 bosses that you've beaten in the previous routes. They have more health and the attack patterns become more difficult to avoid.
Boss 1: Dark Gravity Core
It is based on the hard route settings except the gravity attacks appear more frequently.
Boss 2: Dark Spider
This boss has become more aggressive than before, so it is highly not recommended to stay in between its legs for too long as the legs can get too close to each other at random to avoid successfully.
Boss 3: Dark Twin Metalshell Death Core
Its smaller lasers fire more rapidly and it closes the core quickly to prevent damage from being dealt.
Boss 4: Dark Scrap Wall
Same as hard mode except now it has an exploit. The barriers now spawn blockable counter bullets instead of small unblockable scrap metal that was in hard mode. This means that you can fly pass the arms and stay inside the wall of the boss making it a safe zone.
Boss 5: Dark Viper
Same as before except it now has four options and has access to all weapons from the start.
Omake route
Harder than both hard mode & The Hole of Inferno mode.
Stage 1: G-type Practice
A unique stage to the game that is based on a stage from the first Gradius.
Boss: Overactive Volcano
One mobile volcano that is positioned above you and another one that is positioned below while lasers that come from the front of the main boss restrict your movement. Adding more problems to this threat are counter bullets that can't be blocked while the two mentioned volcanoes move to random spots in the area to shot rocks at you. Good thing the rocks can be destroyed by both standard fire and the force/bits.
Stage 2: G-Type '02 Kai
We get a nostalgia moment as the stage is based on the MSX format and features the 3rd stage from the easy route. The stage itself has been flooded with more moais which be a problem if you're not paying attention to the surroundings.
Boss: Moairatops MSX
Same pattern as before. I forgot to mention something very important about this boss on the easy route. The stage gradually moves to the right as you are fighting the boss, so you must destroy it quickly before the stage becomes too confined to move around.
Stage 3: The Saikyou Ketteisen - Translation: The Strongest Deciding Match
The true final boss of this game is none other than the one that obliterated the final boss in the hard route and saved your ass in the process, R-9Ø - Ragnarok. This boss features the setups used in R-Type: The Third Lightning and is extremely difficult to beat without knowledge of its pattern beforehand. Three speedups is required to avoid most attacks used by Ragnarok. It possesses the mega wave cannon, hyper wave cannon, multiway fire, two bits, the force, spiral laser and homing shots.
