If you die, drink half of your drink. If you die in an explosion finish your drink. If you manage to kill yourself take a shot. If a player punches you to death take a shot.
The winner of the game gets to nominate someone to take a shot of their choice. If a player has a perfect game and doesn’t die every other player must finish their drinks. If someone dies in the toilet, everyone takes a drink apart from the killer.
