You have 6-14 players who need to collect certain items, but one of the players is Satan and wants to kill everyone.
You can hide and use traps to kill people.
It's prettttyyyyy cooooool~
Warning
[spoiler] WARNING:
I underestimated this at the beginning.
The game is pretty much multi-player only, except for having a very bare training thing which doesn't even have CPU's.
This wouldn't be such a big problem if the game community isn't pretty much dead.
The game is new but probably overpriced and the people who do want to play pretty much have to plan a time to be able to play.
You should probably only get this game if you expect it will be worth it without being able to get a lot of play time or if you get a lot of friends so you can play it together. [/spoiler]
