I think that someone had already stolen the dev's brain before he/she even started to conceptualize this game! LOL!

If the World collapsed to the point where zombies roamed it then the only thing that money would be good for is to wipe your own a$$ after taking a dump, assuming that most of the clean toilet paper had already been stolen and hoarded by others!

Don't worry the game is dumb anyways , what is the point of money in a dystopian world full zombies , might as well be collecting bottle caps.
