The Annihilator

Make this one as organized or 'un-organized' as you want.  Basically, two teams of 5 players go into the field and slug it out in this elimination only game.... the bloodier the battle the better!  Make things more interesting by adding more than just 2 five man teams.  The maximum limit is four teams for every acre of playing area.  Place teams in the area so that they are not in line of sight of each other.  To make score keeping easier, the teams may be accompanied by a referee and each team shoots their own distinct color of paintballs.  This game is best in a 30-45 minute time limit.
Here are a few rules to follow....
1. Teams will stay in their starting points until the Start of Game Signal.
2. The team gets a point for each elimination it inflicts on the other team.
3. There are no points for surviving members of the team.
4. All players must begin the game at their flag station (or assigned starting point) and cannot leave that area until the game begins.
5. Players who are hit are out of the game.
6. Players who are eliminated may not, by word or gesture, indicate any intentions or locations of the opposing team members. 
Object of the game: Team with the highest score wins.

Tactical Advantage:  One thing you'll learn REALLY quick.  WATCH YOUR BACK AND FLANKS.  People will figure out really quick that while two teams are slugging it out, it's real easy to drop in and blind side one team and then take off.  Don't hang around, get a couple of eliminations and get out of there.
Best Paintball Equipment to use: any type of tactical paintball marker or competition paintball gun will do.  Something with an electronic trigger is nice; add an electronic hopper to speed your game up even more.
