On Hard, and also no Stasis, the real impossible challenge it would be to play on Impossibe with these conditions, but you need hell lot of a luck since there are times that you have to get close to enemies/melee them and when having red health/ no health will make enemies to strike you with undodgeable quick time attacks 50% of time... Do not ask how many times I died to just to finish it... probably a thousand? Hardest part is the Aegis VII first marker transport room where you only have rotating fans to attack the enemies with kinesis. They are a lot... Anyway, was a nutjob challenge anyway... I would really want to see anyone do this on Impossible without dying!
