Bungie's original Marathon in 1994 put players aboard a colony ship under alien attack, where they fought through maze-like levels and met infected civilians called BOBs that could explode [1]. Uninfected BOBs screamed, "They're everywhere!" while infected ones greeted the player with the warped line, "Thank God it's you!" [1]

The 2026 Marathon is an extraction shooter shaped by modern games such as Hunt: Showdown and Valorant, and it also reflects battle pass culture [1]. Seen side by side, the two games show a sharp shift in first-person shooter design, from early puzzle-heavy maps to today's competitive format [1].

Bungie also used the original game's terminals as inspiration for the reboot, keeping a link between the two versions [1]. One striking thread is the graffiti "THAKGODITSYOU," a creepy detail that appeared in the 1994 game and promotional art tied to the reboot [1].

The comparison shows how Marathon has moved from a story-rich, claustrophobic shooter into a modern multiplayer extraction game, with the original's narrative DNA still feeding the reboot [1].
