Simulated team warfare with compressed air and bb's, instead of bullets, for safety reasons.
Use an airsoft gun to eliminate your opponents by launching pellets at them. Since pellets leave no visible marks “on hit” it relies on almost entirely on honor. The most common game mode is Team Death Match, which is much safer than it sounds.
