Ship:
Buy some healing items when you get on, so you don't get perma stuck in an unwinnable fight against the retarded schoolkids who never miss even though you do.
Go in the room in the corridor with greendoor, use boxes. One has glucose. Inspect the box at the top and use 390831. Use the green door to avoid the asshole she's too much of a wuss to just not let take the glucose.
Talk to the maid. Twice. Go right to the end of the corridor. Boss fight. Use the vent. End vent.
Use the open box. Door. Open box. Open box. Yes.
Done.
Don't buy the magnet, or cheat cash if you do. Its used to get the key for the lady at the second to last white door, but it can't be used until you beat the game for some reason.
If there's another wanna these imma drop it. You just get dumped in an rpg out of nowhere with enemies who do too much damage, have too much hp, never miss, can't be ran from (makes the escape option in the menu very questionable), where losing just puts you in the same fight with the same items, softlocking you if you can't win.
Only stuck with it because I actually like softcore.
