Halo Drinking Playoffs.
Heres how it works.
Get a group of at least 4 people (more will be better for future drunk levels will increase.
Begin playing Halo deathmatch style(all for all)
The winner will take two shots of vodka
The loser will take 4 shots
everone else must take 1
This way, if you lose, you get too trashed to play, and if you win, you wont play as well, giving the middle people a chance to win and get more drunk.
Sweet hu?
