By equipped with 2 or 3, in Smashbox, you compete in hormone-boosted paintball. the maps are small, and the clashes do not last more than 5 to 10 minutes per game.  The advantage of virtual reality is that you don't have to settle for the classic paint gun: exploding fireballs, homing missiles and others, surprises abound.
A big classic for birthdays and clashes between friends.
