Full Marathon trilogy now available on iOS

The original Marathon has been free ever since it debuted on iOS, leading the way for Marathon 2: Durandal to launch last December, also as a free app. Now the final game in the Marathon trilogy, Marathon Infinity, is available on iOS.

Marathon Infinity also debuts on iOS as a free universal app for both iPad and iPhone/iPod Touch devices. Marathon Infinity is a lot like the other two Marathon games on iOS: you get the full original game, but if you want higher-resolution graphics you can pony up two bucks.
