Marathon’s ‘Sever Slam’ open beta weekend is coming later this month

Bungie announced yet another Marathon test during the February 2026 PlayStation State of Play. But this time, it’s one everybody can take part in. The Marathon “Server Slam” weekend (read: open beta weekend) runs from Feb. 26 through March 2 on PlayStation 5 and “other platforms” ahead of the game’s March 5 launch. Turns out the last weeks ’til launch are more of a sprint, huh.
