The generator is the primary object in the Destroy the Generator game mode. The goal is to destroy the opposing team's generator. Generators can only be damaged by the opposing team. As they suffer damage, the generator's sprite changes to appear damaged. Currently, no points are awarded for destroying the generator. Interestingly enough, autoguns will target the other team's generator, allowing for rapid damage, as autoguns have no ammo limit.
Gen_vista (see below) this is a fairly balanced gen map although infiltrators can easily spawn camp so be protective of the generator.
This is gen_vista (you can find this on Travi Riders West Coast)
