What the event actually is

The Marathon Server Slam is a free, open preview weekend meant to stress- test servers before launch and let players try the extraction-shooter gameplay early.

  • You can jump in, level up, and earn preview rewards that carry into launch (like cosmetic unlocks tied to progression milestones).
  • It’s positioned as the final big test ahead of Marathon’s full release on March 5, 2026.

In forum threads, players are treating this as the “real” first impression of Marathon, since it follows earlier, more limited tests and delays.
