...swat3 looks like pac-man . I would agree with ARMA, but my pc shat itself when I tried to run it. IMO, closest battle-type game to AST would be Americas Army. AA2 doesnt require powerful pc and I think there are custom coop map packs to download.Added (15/03/2012, 11:02 AM)

Also, Rainbow Six Lockdown came to my mind. Its more of a MP style game, with more features. Coop is available, too.
