LOS ANGELES--Have you ever wondered what would happen if you crossed Twisted Metal from the PlayStation with Wing Commander: Privateer? Hard Truck Apocalypse: Rise of the Clans might just be that game. We got a look at this stand-alone expansion to Hard Truck Apocalypse at Buka's booth during E3 2006. For those not familiar with the previous game, Hard Truck Apocalypse is a vehicular combat game with role-playing game elements. You earn money over the course of the game, which you can use to upgrade your truck with new weapons like machine guns, cannons, and rockets. You can also upgrade components like engines or armored cabins for extra protection.
