If the Hundred Years' War had been fought with paintballs instead of rifles, it might still be happening, but it'd be so colorful that no one would mind. Experience your own vibrant battlefield with today's Groupon: for $15, you get an equipment-rental package that includes admission, 500 paintballs, a mask and goggles, all-day air, a marker, and the field fee at Paintball Country Ohio in Hamilton (a $30 value).

Open to the public on weekends, Paintball Country Ohio pits groups of friendly fighters against each other in classic paintballing action. A mask and goggles protect your future chin-modeling career while you strafe the battlegrounds with 500 rounds of shirt-splattering field paint, boldly facing oncoming fire like a canvas in a mad painter’s studio. Players crouch behind enormous, squid-inked obstacles on the Hyper Ball Field to dodge the enemy’s stinging volleys, or gather the troops and sneak through 40 acres of woods in search of new states to claim for America. Suburban soldiers can stage a heroic rescue mission on the multi-level Fort Field, where four buildings become a neighborhood strewn with lively rifle fire. Should you tear through your share of ammo on a kamikaze mission or mistake them for extra-juicy gumballs, additional sets of 500 ($14) and 2,000 paintballs ($45) may be purchased in the pro shop. Pizza and drinks are also available for refueling after a hard day of wreaking havoc.
