The Marathon Trilogy is now available for free

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.
