One of the iPhone and iPod Touch's answers to Advanced Wars now supports online play.
Earlier this week game developers Oyaji released an ad-supported free version of the game that allows players to battle one another over a WiFi connection.
The game, which uses OpenFeint for online support, allows you to select turn time limits ranging from 5 minutes to 24 hours. There are also four game modes: Conquer, gold differ, assassination and annihilation.
If you'd rather not deal with the ads, which are pretty low-key, and want access to the full game, including several single-player campaigns, you can buy the full version of Mecho Wars for $.99 which also includes the online play.
