Bungie’s Marathon reboot has been delayed from its original September 23 release date to an unknown date.

In a news update shared to Bungie’s official website, the Marathon dev team suggests feedback from the extraction shooter’s alpha playtest, which ended in early May, is at the heart of the delay. No new release date was revealed.

“The Alpha test created an opportunity for us to calibrate and focus the game on what will make it uniquely compelling—survival under pressure, mystery and lore around every corner, raid-like endgame challenges, and Bungie’s genre-defining FPS combat,” reads the news release.

“We’re using this time to empower the team to create the intense, high-stakes experience that a title like Marathon is built around. This means deepening the relationship between the developers and the game’s most important voices: our players.”
