Shoot Many Robots

P. Walter Tugnut, a hillbilly who lives in the countryside of a rural area in his dilapidated RV, has several weapons, ammunition, and beer, awaiting the eventual robot apocalypse. One day, a previously abandoned Chernobyl-style factory begins producing robots on its own. This is the day that Walter has been waiting for his entire life. He sets off in his RV on a robot-killing rampage, hoping to save humanity from an onslaught of deadly robot menaces.

This is an indie side-scroller that supports 4 player co-op, although in the experience of those who have played 4 player co-op, the lag gets pretty bad when lots of people are shooting, even on fast internet connections.
