Grab a friend to play my new mini-game DUEL!

RED: W to load S to duck D to shoot

BLUE: I to load K to duck J to shoot

Shoot your opponent OR load 7 bullets into your gun to win. Duck to avoid being shot. Shooting or loading before the green light goes on will temporarily freeze your character, so be careful!
