Anyone who's been watching EA knows that the publisher's going to be tethering portable spin-offs to its big releases. Last year's Dead Space game for iOS and Android proved such games could be great and yesterday we saw the debut of Mass Effect Infiltrator. This sector's a big deal for EA.

So, it's surprising that Battlefield 3: Aftershockwhich we previewed last summer—just popped up into the App Store today with no fanfare.

What's even weirder is that the game's being sponsored by Act of Valor. The upcoming action movie features active-duty Navy SEALs and is for all intents and purposes an attempt to get the energy of Call of Duty—you know, the FPS rival to Battlefield 3—on the silver screen.

That sponsorship means that the game is free, though, so it costs nothing to try out the multiplayer game.
