"Aleph One" is an open source continuation of Bungie's Marathon 2 game engine. Its available for Windows, Linux and Mac OS X.
Recently they released version 1.0 of their game engine which is a cross platform game engine and brings the classic Marathon games, as well as fan-made modifications to the modern Mac, Windows PC and Linux platforms.
To celebrate the release, Aleph One team is providing a remake of Bungie's Marathon Game Trilogy absolutely free to download.
This new Aleph One game engine enhances Bungie's original Marathon games with modern OpenGL shader support, Internet co-op and multiplayer, modern mouse-look and gamepad support and plugin support for modifications.

The Marathon game trilogy comes with following 3 games:
- Marathon
- Marathon 2: Durandal
- Marathon Infinity
Marathon - Alien forces have boarded the interstellar colony ship Marathon. The situation is dire. As a security officer onboard, it is your duty to defend the ship and its crew.
This release is a meticulous conversion of the original game to the Aleph One engine, with many details and battles restored that were missing from the earlier "M1A1" release.
It has been updated with a modern HUD, high resolution graphics as well as extensive changes to the scenario to create the most authentic Marathon experience since 1994.
Marathon 2: Durandal - Fresh from your triumph on the starship Marathon, you are seized by the rogue computer Durandal to do his bidding in a distant part of the galaxy. Within the ruins of an ancient civilization, you must seek the remnants of a lost clan and uncover their long-buried secrets. Battle opponents ancient and terrible, with sophisticated weapons and devious strategies, all the while struggling to escape the alien nightmare.
This release of Marathon 2: Durandal includes the classic graphics, and revamped high-definition textures and monsters from the Xbox Live Arcade edition.
Marathon Infinity - Marathon Infinity takes the closed universe of the Marathon series and blows it wide open. The solo/co-op campaign, "Blood Tides of Lh'owon," is a 20-level scenario sporting new textures, weapons, and aliens. More than that, the scenario sheds a surprising new light on the story's characters and the meaning of events. Having defeated the Pfhor and reawakening the ancient remnants of the S'pht, the player now faces a world where friends become enemies and all is not what it seems.

^^ I can see you have TuneUp Utilities installed in your Windows. Try to apply the theme using TuneUp Styler. It seems TuneUp has messed up with something.
