What’s Marathon Cryo Archive release schedule?

Marathon’s Cryo Archive is a weekends-only endgame map

Bungie’s Cryo Archive, Marathon’s fourth map, is set to launch on Friday, March 20, and it’s structured as a weekends-only “raid-style” PvPvE experience. The community work to unlock it included a multi-step ARG and grinding objective, and once opened, the map became accessible for play only during weekend windows.

Bungie has also explained that Cryo Archive is aimed at endgame challenge content rather than standard public rotation. In addition to the launch timing, Bungie provided further details about how the map operates at launch and what kind of high-tier difficulty players should expect once they can queue in.

What players should know

• Endgame focus: Cryo Archive is positioned as Marathon’s toughest/most raid-like location.
• Access model: it opens for play during weekends only (not a weekday staple).
• Prerequisite: before it could be played, the broader playerbase had to complete the ARG/unlock sequence in stages.

No exact daily hours for the weekend window were included in the provided story set beyond the general weekends-only framing and the Friday start date.
