Bungie is pulling back the curtain on Marathon's technical backbone just days before its final Server Slam playtest. In a detailed blog post published earlier today, game director Joe Ziegler outlined the studio's comprehensive approach to networking, security, and player protection for the extraction shooter launching March 5th. The measures aim to deliver a cheat-resistant experience from day one, directly addressing concerns from extraction genre rivals like ARC Raiders.
Marathon, a reimagining of the 1990s FPS series, enters a competitive PvPvE landscape dominated by Escape from Tarkov and ARC Raiders. After a 2025 closed alpha drew a lot of mixed feelings on pacing and polish that quickly prompted an indefinite delay Bungie iterated extensively and worked hard: smarter AI Runners, refined time-to-kill, visual upgrades, and proximity chat for emergent alliances. The Server Slam (Feb 26th, 10 AM PT to Mar 2nd, 10 AM PT) offers a free stress-test on PS5, Xbox Series X|S, and PC with no pre-order required that grants players exclusive launch rewards for milestones. Check out the clip below:
Dedicated Servers and Authoritative Combat
All Marathon servers are dedicated and fully authoritative on critical actions: shooting, looting, and interactions. This server-side validation minimizes client-side manipulation, a staple in Bungie's Halo and Destiny multiplayer. "Key combat and looting actions" run server-verified, reducing exploits like aimbots or loot dupes prevalent in peer-to-peer titles.
New networking tech ensures responsive movement: "Players' actions feel snappy," per Ziegler, with optimized prediction for low-latency firefights across 60-player lobbies. Reconnects mid-run are supported so if Bungie's servers hiccup, starting gear returns automatically (player internet issues do not qualify).
Fog of War: Anti-Wallhack Innovation
Marathon's standout feature: Fog of War, a server-enforced system limiting client map knowledge to visible/explored areas. Wallhacks and loot revealers lose potency as players can't see distant enemies or stashes. "The Fog of War system runs on the game server to limit the regions of a map that individual player clients have knowledge of," the blog states. This echoes Valorant's server-side fog but tailored for extraction: dynamic visibility ties to position and line-of-sight.
BattlEye + Rebuilt Security Stack
BattlEye anchors the anti-cheat, bolstered by a "ground-up rebuilt game security stack." Machine learning detects anomalies, behavioral analysis flags suspicious patterns, and manual reviews handle appeals. Policy: permanent bans forever, no second chances. "Anyone found cheating will be permanently banned from playing Marathon forever," Ziegler emphasized no strikes like ARC Raiders' controversial three-tier system.
This stance contrasts Embark's ARC Raiders, where CEO Patrick Söderlund defended leniency but faced player anger over dupes and aimbots. Marathon's zero-tolerance aligns with player demands, potentially setting a genre standard.
