Auto Assault was a 3D MMO from NetDevil and NCSoft. Originally released in 2006, most of Auto Assault's gameplay took place in a vehicle, which served as one's avatar for most of the game, except for time spent in towns. Taking its inspiration from sources such as the Mad Max films and Greek mythology, the game's post-apocalyptic setting was the backdrop for a story that took place after an indirect attack by aliens that left Earth uninhabitable and forced humanity underground. Trapped by circumstances, this led to research in order to combat the problem. Players could choose to belong to one of three races --Humans, Mutants created as a result of the contamination, or Biomeks, soldiers genetically engineered by humans to be immune to mutation. Each race viewed the others negatively in some form, while each race also got certain advantages and classes unique to them.

Players could choose to be active at any point in time in one of two layers on each server. Choosing the PvP layer enabled skirmishes and battles between players, while the PvE layer was useful for completing quests. PvP bent to the action, with everything from racing to direct combat modes at its heart. Each side faced the others in a series of battles using cars, trucks, motorcycles, and even tanks which from the players' end was experienced as third-person perspective combat.

Due to low subscriber numbers, it was announced that Auto Assault would shut down as of August 31, 2007.
