Doctrine, a vampire-inspired Support hero allied with Doomfist, is playable now in a limited-time trial through Sept. 14 before joining the roster with Season 5 on Oct. 6.
Season 5 also adds Escort map Watchpoint: Grímsvötn—an Icelandic prison tied to Doctrine’s story—and major reworks for Sombra and Roadhog, with Sombra shifting from Damage to Support.
Blizzard framed the reveals as the close of Overwatch’s first year-long story arc, Reign of Talon, while teasing Hero 55 and a broader 2027 roadmap due at Overwatch Spotlight in February 2027.
BlizzCon rewards and events round out the update: players can earn one Mythic bundle from Seasons 1-14 by playing a game by Oct. 5, while the World Cup finals feature 8 teams plus LE SSERAFIM and YOASOBI performances.
