Steel Chaos is a massively co-op online game. In the shared persistent world of Steel Chaos, players are hovertank pilots fighting a desperate war against the alien machines. Working together, the players must fight back, smashing the invaders into junk and retaking the world for humanity. Players secure and exploit natural resources, then construct fortified outposts to consolidate their gains. Using these resources, players develop new technologies and design new hovertanks to use them. Steel Chaos is an MMO, but it's no theme park. Every enemy robot you crush stays crushed. Every enemy factory you raze stays razed. Will you and your fellow hovertank pilots have the skill, coordination and strategy to save humanity?

User Summary Steel Chaos was a cooperative 2D top-down PvE MMO, play was in casual groups working for the overall victory goal through whatever method they wished. Levelling was a cooperative effort via Research Projects to unlock better equipment usable by everyone, with a shared total cost paid for by players gathering resources and then choosing how to allocate their points for best strategic advantage. The enemy tanks were procedurally generated, and the players could switch between tank classes at any time to adapt to the changing battle. Additional class choices could be developed as play progressed. Movement was via keyboard and mouse input: WASD/QE for movement, and JKL; to fire the four weapons/abilities, using mouse cursor to aim, and there was an in-game chat. Steel Chaos was an entrant in the 2010 Independent Games Festival. The game began development in May 2009 under the working title GameTwo. It was released later in 2009 and ran via Flash plugin on the official website http://steelchaos.com. The site is now defunct.
