Prior to making Halo for Microsoft, Bungie cut their teeth making games for Windows rival Mac OS for years. Now, their classic shooter Marathon is finally coming to PC, decades after its debut.

Originally released back in 1994 only for Mac OS, Marathon is finally coming to Windows (via Steam) thanks to the team behind Aleph One, the open-source continuation of Bungie’s Marathon 2 game engine. A release date wasn’t confirmed though Marathon is coming “soon.”

Lauded as a classic sci-fi shooter, Marathon is considered one of the first shooters to offer vertical aiming. Its re-release promises widescreen HUD support, 3D filtering/perspective, positional audio, and 60+FPS interpolation “just in case the original is too authentic.”

Marathon was followed by two sequels, Marathon 2: Durandal and Marathon Infinity. While its direct sequel came to Windows a year later, the original Marathon and the final game in the trilogy never got ported off Mac OS.

Bungie more recently announced a full revival for the IP titled simply Marathon, for Windows and modern consoles. They’re billing the successor as a sci-fi extraction player-versus-player shooter – read more here.

Here’s a brief blurb on the classic game:

Alien forces have boarded the colony ship UESC Marathon in the Tau Ceti system, in orbit around humanity’s first interstellar colony. The situation is dire, and as a security officer assigned to the Marathon, your duty is to defend the ship and its crew from the alien threat.

This classic 1994 Bungie™ FPS had a foundational influence on the genre, and is now maintained by the fan community. Experience authentic game play using the original data files, with optional widescreen HUD support, 3D filtering/perspective, positional audio, and 60+ fps interpolation, just in case the original is too authentic.

Classic Marathon is powered by the Aleph One engine, which is available under the terms of the GNU General Public License (GPL) Version 3.
