Counter Strike: Global Offensive
2 - 4
All players must be playing the game. Every time you get a kill, the person to your left has to take 2 drinks. If you die you take 2 drinks. If you die during a round without getting a kill you have to take 3 drinks.
If you defuse the bomb, everyone else must finish their drink. If your entire team dies without getting a kill, then you must all finish your drink. If a player gets a triple kill or higher, they are immune from drinking the next round
Once all rounds are over the player with the most kills get to choose someone to take a shot.
