X-COM: Enemy Unknown gets multiplayer mode, goes on sale

X-COM: Enemy Unknown for iOS has been updated, adding multiplayer support. The game is also on sale for $9.99, 50% off the normal price of $19.99, through October 13.

Multiplayer is asynchronus, and uses Game Center. As in the single-player campaign, you create custom squads, either human or alien, and challenge your Game Center friends to matches. This update also optimizes X-COM for iOS 7, and fixes a number of bugs.
