'I want to play a game. You don't know me but I know you. To live you will have to sacrifice a piece of yourself. Or perhaps a few pieces. You better hurry up. Live or die, make your choice.'

Go through a maze of old rooms, where you can find yourself in danger everywhere. A horde of zombies wants your skin, FIGHT THEM!
Open doors, choose a weapon, collect coins, seek healing!

The path won't be easy, it will be a more personal sacrifice than you think.
Give up a part - or many parts - of yourself and unlock the exit. Act quickly, but choose wisely.

And here you are, 

broken by choice.
