Once a player is marked with a paintball he or she must raise their marker in the air to indicate that they are eliminated from the game.
At any point in the game a player may be eliminated or call themselves out for any reason. The paintball must break and leave a quarter size mark or larger to be eliminated.
Surrender:
Surrender is always an option and most times a wise choice. Players are allowed to call themselves out at any time for any reason.
If a player is closer then 20 feet away from another player he or she is required to offer surrender. Shooting a player closer than 20 feet away is not recommended.
