Of course these basic rules can be applied to most FPS which have split screen multiplayer.
- If you die, drink
- If you're killed by a headshot, take two drinks
- If you use a killstreak reward, take a drink
- If you insult or abuse another player (for example, say you slept with their mother, call them a "*@#!", teabag their corpse), take a drink
- If you hear this from other players, take a sip and hope you still have the use of your legs at the end of the match
- If you hear a character say oorah, or some derivative thereof, then take a drink.
- If you pick up a new weapon, drink.
- If you change class, drink. Choose wisely.
- Every time you're killed by lagging out, take a drink.

- Upon switching weapons
Take a shot:
- Upon completing a level
- Upon being killed by a grenade
- Upon finding an intel item
- Upon using any kind of heavy weaponry (rocket launchers, UAV support, C4 charges, mounted guns)
