Aleph One is the free and open-source continuation of Bungie's Marathon 2: Durandal engine, allowing players to experience the original Marathon trilogy—Marathon, Marathon 2, and Marathon Infinity—on modern systems. This long-running fan project, which began after Bungie released the source code around 2000, runs on macOS, Windows, and Linux. Beyond the classic campaigns, Aleph One powers dozens of community-made scenarios and total conversions with new weapons, monsters, and storylines. The engine supports both single-player campaigns and peer-to-peer multiplayer for up to 8 players online or over LAN, with optional account tracking and monthly leaderboards at lhowon.org. A native Apple Silicon build has been confirmed running on Macs in the Rosetta Check community.
