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.
