"Go down into the dungeon. Kill everything you meet.
Backstab your friends and steal their stuff. Grab the treasure and run."

Highly entertaining to play as you build up your character and beat the
monsters. Choose from helping people out, swapping items and sharing
treasure, or helping the monsters beat them and reap the benefits all for
yourself. We will provide the base game, but expansions are welcome!
