Boulder is a medium-sized map involving the RED and BLU teams competing for space on a series of boulders. BLU owns a radio station, the BEACON, and RED owns Old Geezer's Draft Beer. These businesses are just umbrella terms for the real deal, which is harvesting the boulder's resources. Will Old Geezer's manage to make a new type of beer with the minerals in the boulders, or will BEACON broadcast a new type of rock music with their new resources? Play on Boulder to find out!
