Marathon Season 2 injects Sentinel class and a free Open Play Week

Bungie outlines Marathon Season 2 for 2026, adding the Sentinel post-launch class that defends space, can disable grenades, and boosts nearby teammates, plus a darker Night Dire Marsh map, two new weapons (KKV-9SD SMG and D54 Battle Pistol), and a revamped Cradle progression system driven by WEAVEworms. An Open Play Week from June 2–9 on Steam, PS5, and Xbox Series X/S lets everyone try the game with cross-progression; Ranked play begins June 14, the Cryo Archive zone returns June 11, and the season emphasizes PvE-focused, varied gameplay while progression carries over.
