A new update adding multiplayer is available for XCOM: Enemy Unknown on iOS. Multiplayer in XCOM on iOS is asynchronous, allowing players to conduct turns at their convenience.

The update also adds multiplayer leaderboards, optimizes the game for iOS 7 and fixes a few lingering bugs. And to celebrate this new update, XCOM: Enemy Unknown is on sale for $10 until October 13.

XCOM: Enemy Unknown made its debut on iOS back in June, in a full mobile port we found to be on par with the console and PC offering. XCOM: Enemy Within, a new expansion for the PC and console version of the game, is due on November 12.
