Extreme space restriction, large mobs backed by archviles or cybers... yes this is the quintessential sunlust map.
As most people would agree, the blue key area with all the revs is definitely the deadliest so i try to get that one over with first. I actually use speedrunning tactics i learned from other players in order to increase my odds of survival. The rest of the map went ok-ish.
I was slow at the earlier noble/vile fight because i was worried about saving rockets, maybe i should consider spending them all and then manage without? I dunno.
