Marathon director Joe Ziegler discussed Bungie's plans for upcoming seasons of Marathon, highlighting the introduction of a new map featuring "alien elements and mind-warping debuffs" and the next Runner shell, Sentinel, which will offer a defensive kit. Two new PvE-focused modes will debut in Season 2: one experimental mode at the beginning of the season that combines PvE with a light touch of PvP, and a second PvE-only mode focused on crew objectives. Ziegler emphasized that while PvE options are being introduced, PvP will remain a core aspect of the game. Further details on Season 2 changes, including faction progression enhancements and new runner stat boosts, will be revealed the week of May 25.
