Now I as have made through this shitty level with 1 mid level saves. Now I'm pursing getting through this nightmare alive. I see slight chance I can make it till 15th. Since someone may find failures interesting. I will show you the locations -- one each day -- I usually tend to fail at. There are many. And I can say roughly 1 : 50 is the chance you get to the yellow key intact... Even if you do your best.
So here is the reason #1 I keep failing I can say 3 in 4 times I end up like this, the corridor made so the green platformers that pop out from the ceiling and the floor can shoot in. The class 2 drone is placed so you cannot destroy it before the entry. But somehow those class 1 drones don't push it out from that corridor, I cannot get past it without bumping it. Trust me I tried everything. corner sniping with lasers, hoping that a concussion missle blast radius will kill it but no avail. It's too far inside.
Also you must trichord to get in and keep trichording making it very hard to avoid the lasers getting stuck got toasted by rockets.
You only chance is that you can time the closure of that door so rockets bang the door instead. But it's quite hard to feel the right time.
