XCOM2 wotc ironman legend PS5 -black market strategy- episode 42 ‘skullmine 🎲’

So this is around the 6th attempt to skullmine for a facility lead.
I don’t know if there are any significant factors in swaying a positive result??
I’m guessing it’s just completely random.
There’s only one open available facility left in order to reduce the avatar project so really need this to work… 🤞🏻🎲
This is also where you can fail in the campaign where you run out of ways to reduce the avatar project…it runs out…GAME OVER!
Having successfully completed Ironman runs… i think the game will offer up enough ways to reduce the avatar project but crucially you do have to utilise them at the right moments….essentially if your down to the last day of the avatar project then it’s time to sabotage an advent facility!
Unedited continuous gameplay.
