Marathon Server Slam: 11 Tips From the Game Director and What Players Need Before the Open Playtest

Why this matters now: If you plan to jump into the marathon open playtest this weekend, your actions will shape the game's live systems and also bank exclusive launch rewards. The Server Slam is both a hands-on preview and a global stress test that runs from Feb. 26 at 10 a. m. PT / 1 p. m. ET through March 2 at 10 a. m. PT / 1 p. m. ET—use the time to learn, earn, and help smooth the March 5 launch.

Who should treat this as a rehearsal for Marathon’s full release

This weekend is aimed at players who want a head start on gameplay, progression, and the technical realities of a live service shooter. The Server Slam is explicitly a preview—play for free on supported platforms, try core loops, and expect limited content compared with launch. If you want to arrive on March 5 comfortable with gear, extraction basics, and the flow of a match, this is precisely the opportunity to do so.

Event basics and schedule

The Server Slam begins Feb. 26 at 10 a. m. PT / 1 p. m. ET and ends March 2 at 10 a. m. PT / 1 p. m. ET. It’s being run as an open preview weekend (a final beta) so many players can join and test global infrastructure ahead of the March 5 launch. Play sessions during the Server Slam are free for PC and console participants; cross-play and cross-save are enabled for the weekend.

What’s playable, what’s withheld, and platform notes

• Playable platforms for the Server Slam include PC and current-gen consoles; the game will also be visible on a major PC festival storefront during the weekend.
• The Server Slam is a slice of the full title: not all maps or features are included in this preview. At full launch (March 5) and into Season 1 you will see additional zones, factions, contracts, gear, deeper progression, and Ranked play.
• At launch the game will include two additional maps listed for release: Outpost and Cryo Archive (Cryo Archive is noted to arrive during Season 1). A sixth Runner Shell called Thief is slated for launch but will not be present in the Server Slam build. Ranked mode is also scheduled to arrive in Season 1.

Rewards, progression banking, and how they arrive

Time in the Server Slam converts into launch-day rewards. Complete objectives now to bank caches and cosmetics that unlock once the game goes live on March 5. Reward tiers that will carry forward are:

• Complete your first mission: Standard Arrival Cache
• Reach Runner Level 10: Enhanced Arrival Cache (Green)
• Reach Runner Level 30: Deluxe Arrival Cache (Blue)

Everyone who completes the introductory mission during the weekend will also unlock a Beta. exe emblem and a Complex Study player background as exclusive marks for early participants. Cosmetic and loot rewards will be delivered after the March 5 launch; rollout may take some time, so if rewards don’t appear immediately in your inbox, be patient.

How the Server Slam functions as a stress test

This weekend’s priority is technical: the team will turn systems on worldwide, invite as many players as possible, and watch core behaviors—players will log in, crew up, infil, exfil, log out, and repeat while engineers monitor performance. Staff will be standing by to address issues and make live adjustments; broken systems are treated as valuable data that will be used to improve the March 5 launch experience.

Gameplay setting and in-session goals

Marathon takes place on Tau Ceti IV, a derelict space colony where Runners and hostile UESC security forces contend across maps that include futuristic research facilities and lush surface areas. The narrative setting is the year 2893, 99 years after the events of the original Marathon game and centuries after the colony’s founding. Players will scavenge maps, fight both other players (PvP) and AI enemies (PvE), pursue better loot, and work to extract—progress that yields cosmetics, seasonal power, and more. Planet surface activity is just the start; in later content players move toward the Cryo Archive and the first floor of the UESC Marathon orbiting above.

Here’s the part that matters if you’re playing this weekend: the Server Slam will not include every map or future feature, but it should provide a large chunk of the core game loops so you can test extraction, scavenging, and combat under live conditions.

• Key takeaways: play to learn the extraction loop; bank progression now to secure launch caches; expect platform-wide cross-play and cross-save; don’t expect every map or Runner Shell during the preview; treat instability as expected and useful.

If you’re wondering why this keeps coming up: the team views the Server Slam as both a marketing preview and a technical rehearsal. Your participation helps them identify real-world bottlenecks before full launch.

Game director Joe Ziegler has shared 11 tips aimed at beginners to help players get more from the Server Slam; those tips were distributed ahead of the weekend and were edited for clarity by a gaming publication. Use them as a starting point while you learn the maps and extraction priorities.

Micro timeline: Feb. 26 (10 a. m. PT / 1 p. m. ET) — Server Slam starts; March 2 (10 a. m. PT / 1 p. m. ET) — Server Slam ends; March 5 — full launch and reward rollout begins.

It’s easy to overlook, but this weekend’s activity is both an opportunity to earn exclusive cosmetics and a practical rehearsal that will affect how smoothly launch day arrives.

Writer’s aside: Expect some rough edges during any stress test—engineers will be watching and patching, but player reports and high-concurrency behavior are the clearest path to fixes before March 5.
