Shoot Many Robots

You take control of P. Walter Tugnut (The “P” stands for “Pickles”), a regular guy who stockpiles guns, ammo, and beer in his dilapidated RV awaiting the inevitable robot apocalypse. When the abandoned factory in the distance begins producing robots on its own, Walter sets off in his RV on a robot-killing rampage, hoping to save humanity from an onslaught of robot hordes.
