How to play Marathon on Mac?
There's something poetic here: Marathon, Bungie's very first franchise, was born as a Mac exclusive in 1994. In 2026, the series returns as a full-scale PvPvE extraction shooter, but without a native macOS version. With Shadow PC, you can play Marathon on any Mac or MacBook from day one, with the full power of a high-end Windows PC in the cloud. Drop into Tau Ceti IV, choose your Runner Shell, and fight your way to extraction, all from your Apple device.
Play Marathon on your Mac with Shadow PC
Shadow PC gives you a complete Windows gaming PC in the cloud, so you can install Marathon directly from Steam, just like any PC player. Whether you're coordinating a three-Runner squad through Dire Marsh or going solo as a Rook with nothing to lose, Shadow delivers the low latency and consistent frame rate that a competitive extraction shooter demands. No Windows machine required, not a single gigabyte used on your Mac.

Marathon: the colony is lost. The loot is yours.
Set in 2893 on the abandoned colony of Tau Ceti IV, Marathon is a PvPvE extraction FPS from the creators of Halo and Destiny. Drop in, scavenge, fight rival crews and AI factions, then extract or lose everything.
Pick from seven bio-synthetic mercenary classes at launch, Destroyer, Vandal, Assassin, Recon, Thief, Triage, or Rook, each with unique Prime and Tactical abilities. Layer in moddable weapons, body implants, and Core upgrades to build your exact playstyle.
Tau Ceti IV launches with three ground zones, Perimeter for beginners learning the basics, the hazard-filled Dire Marsh where a high-gear dropship mid-run draws every Runner in the area, and the brutally vertical Outpost where PvP encounters are near-unavoidable.
The Heat System replaces traditional stamina: sprinting, double-jumping, and sliding all generate heat, and overheating slows your Runner at the worst possible moment. Manage your movements, manage your contracts, manage your squad, and extract before someone else extracts you first.
Proximity Chat and live alliances directly on your Mac
Marathon's Proximity Chat system lets you negotiate real-time truces with rival crews to take down powerful common enemies, then betray them the moment it's convenient. Playing via Shadow PC on your Mac, you're running the full Windows version, which means you're in the same lobbies as PC, PS5, and Xbox Series players, with complete cross-play and cross-save supported from day one. Your Runner progression, your loot, your Vault, all of it follows you seamlessly across devices and sessions.
