Permadeath, lame
Also there's this Co-op mode called "marrying". It's optional, and if you do "marry", you can quit at any time.
It says I can't unlock that until I'm level 18, what do I do?
Sadly, there aren't any options for grinding levels. You'll just have to continue on until you get to level 18.
Ok, is there any requirements I need to play the mode?
You can unlock this power-up called "booze" when you reach level 21.
There are tons of cheatcodes you can use to get that before level 21.
It took me 9 months to install this game, and so far it isn't worth it. Does it actually kick off at level 18?
