EA has released a free iOS title sporting the Battlefield name. Battlefield 3: Aftershock is now available for iPhone and iPad, and shares cross-promotional duties for both Battlefield 3 itself and the upcoming war film, Act of Valor. It features online multiplayer and three weapons.

The bad news? It's missing many previously promised features and the user reviews are pretty harsh. Touch Arcade reports that earlier previews promised a single-player campaign and enemy wave mode. Players can unlock a weapon by watching a trailer for Act of Valor, and the game features regular ads for the movie, which is presumably why it's offered for free.

User reviews of the app complain of glitches and control issues, and so far the rating stands at 3.5 stars. If you want to try it out for yourself (and why not, it's free), it requires a iPhone 3GS or higher with iOS 4.0 or later installed.
