I've attempted to use the iOS app several times, but it seems to freak out the server and nearly instantly hit flood control for some reason I never identified.
Played for a few hours tonight. If you like Assassins Creed and GTA, you should like this. It doesn't want to recognize my game controller though, so that's a bummer.
Sparta now has it's very own Insurgency (http://www.playinsurgency.com) dedicated server! Find it in the server list as "LOSC Legion of Sparta"! Come one, come all!
