EA has plans to release a multiplayer demo for the Xbox 360 next week, which has a bit more than you would think.
According to Videogamezone.de that the demo will feature two modes, Team Instant Action which is basically a fancy way to say Team Deathmatch. The other mode is “Crash Site” which appears to be a mode where you fight off alien pod invasions for population control. Both game types will take place as on the Skyline map.
Currently there is nothing officially saying its Xbox exclusive but its not looking good for other platforms.
