Paintball grenades
People who are into airsoft and paintball have always one mission in mind when they participate in every gaming session: to take out the enemy. Thus, they always needed that extra advantage to get ahead of the others, whether it be in the form of a piece of equipment, a new team member, familiarity with the place, or a new strategy.
Paintball grenades may very well do the trick. After thinking of a successfully planned strategy in letting the enemy think the odds are stacked against you, with just one surprising throw of a paintball grenade at them, the tides have now turned in your favour!
