Of Tanks and Demons III

In late 2020, the gates of Hell open and demonic hordes pour out — impervious to conventional weapons. The human race appears to have no defense. Then Dr. Gusev and a group of American scientists develop photon cannons capable of tearing demon flesh apart and install them on advanced tank models built by Greenrunner Industries. The catch: the tanks can only be operated by the engineers who designed them, and those engineers are sitting in prison, convicted as war criminals for opposing the government. With extinction on the table, a compromise is reached. Travis Greenrunner and his team earn their freedom — one demon at a time. A tank-based shoot-em-up about engineers who became soldiers by necessity.
