This is not a game for the faint of heart and contains some rather dark fantasies.
Forget the hundreds of lines of dialogue you won't even read - in The Bunker, you'll get straight to the point!​

You've been forced into an underground bunker with 3 rooms and a hot, big-boobed milf. Overcome with a sudden, insatiable lust and nowhere to go, you'll corrupt and harass the milf until she's completely beholden to your will.

In order to fully corrupt the milf, you need to increase the milf's submission, build on your tech skills, and become more depraved. With low depravity, you'll have no motivation to harrass the milf. With low submission, the milf won't take it. Your tech skills will also give you access to new scenes which will speed up your depravation and the milf's submission.

During your time in the bunker, you'll harass the milf to increase her submission and corruption by walking in on her during her baths, oogling her during yoga, and eventually by demanding lewd acts.

The game combines your typical visual novel with a sandbox feel so you can explore the game's rooms and choose the scenes you want to find and explore next.
