Marathon, Marathon 2: Durandal and Marathon Infinity could be considered the fathers of first-person shooters. But unless you have a computer that can run Mac OS 9, you couldn’t relive fond memories of destroying a Pfhor armada…until now. Along with compatibility with OS X, Windows and Linux, developers have also added improvements such as modern OpenGL shader support, high resolution graphics, Internet co-op and multiplayer, and plug-in support for modifications…all for free.

This week on the Free Apps Roundup: Get ready for carnage; Bungie’s classic FPS, Marathon, has made its way to the App Store sans charge. But that’s far from all. TWC has updated their iPad TV app, MS updated Bing, and I found a bunch of other great apps, not to mention a bunch of limited time freebies you aren’t going to want to miss.
