Classic Marathon

Classic Marathon is a community-maintained release of the classic 1994 Bungie FPS, powered by the open-source Aleph One engine, which launched on Steam on May 10, 2024. The game has received a consistent stream of updates since launch. Feature releases include Aleph One 1.9 (July 12, 2024) with dedicated servers and major networking improvements, version 1.10 (August 23, 2024) adding Steam Workshop support, and version 1.11 (August 29, 2025) introducing native Steam Linux support, substantial audio improvements, new sprite rendering options, and replay film support. Bug-fix releases have accompanied this pattern: version 1.8.1 on May 14, 2024, version 1.10.1 on March 3, 2025, and most recently version 1.11.1 on October 1, 2026 — a security and bug-fix patch urging net game players to update immediately. Major feature releases have appeared at a cadence of roughly every 6–12 months since launch (July 2024, August 2024, August 2025), with maintenance patches filling the gaps. As of today, October 1, 2026, the most recent major feature release was version 1.11 on August 29, 2025 — approximately 13 months ago, placing the project at or near the outer edge of its established cadence window. However, the security patch released today (1.11.1) confirms the developer team remains actively engaged with the project. No developer statement has declared the project complete or indicated that development is winding down. The open-source, community-driven nature of the project and its sustained update history indicate ongoing maintenance and enhancement.
