Paintball is catching its popularity here and many have tried out this game. I still have not though. With this game, you can act out what you watched on those action movies; shooting and killing others. So violent eh but better than killing people for real. :P
In this game, normally the paintball equipments are supplied for you at the paintball field but you can get you own if you want too. Check out Ultimate Paintball. They do sell all kinds of items relating to paintball. You can get the guns, gear, tanks, mask or even the dye paintball from them.
