Fragapalooza

(from the rules)
Isn’t it fun to blow the crap out of your friends while playing video games? Don’t you get a sense of smug self-satisfaction? Now get that feeling without getting motion sickness or eye-strain. Fragapalooza is a miniatures game of multi-player, shoot-‘em-up, video game-style action for 2 to 10 players.

The basic setting of Fragapalooza is your standard sci-fi shooter like Halo or Unreal. Players frag one-another on a board strewn with deadly weapons and fantastic power-ups. Change the names of the weapons, throw down some appropriate terrain and you can turn the game into WWII action, a western, spy thriller, etc.

Edit: The second edition of this game is now named "Frag-O-Rama".
