Bungie has announced a delay for its game Marathon, which will not launch on the originally scheduled date of September 23rd. A new release date has not been set, but an updated launch window will be communicated in the autumn. The delay follows a mixed reception from a recent alpha playtest, and Bungie aims to enhance the game's survival gameplay, enrich the game world, and improve the social experience based on player feedback. The decision for the delay was made after extensive discussions within the development team, emphasizing the importance of creating a compelling experience characterized by survival, mystery, lore, and Bungie's first-person shooter combat.
