I’ve never engaged in any Paintball wars myself, so I thought it was all guns. Nope. Check out the Spraymore series from Paintball Landmines.
It’s a complete line of advanced and reusable Paintball Landmines that range from tripwire models to wirelessly detonated versions. Damn, these things are going to make one heck of a mess. Wirelessly detonated models can be triggered from up to 100 feet away.
