It's a very original strategic shooter.
Yeah, I liked that game, but the freemium system ruined it for me.
All the Modern Combat and NOVA games have multiplayer, and they're fun as hell. Trigger Fist and Doodle Army 2 are great too, that is, if you have a good conmection for both. SAS Zombie Assault 3 makes an excellent online DSS, if you can find people to play with. If you have a friend with an iDevice, you can play Minigore with them. Zombieville USA 2 is the best arcade shooter, and also has co-op. Vs Racing 2 is an excellent top down racer, and technically has multiplayer. RAD Soldiers is a turn based strategy game, and that also has multiplayer.
Hope this helps.
