What to expect in Marathon Server Slam Open Test

As mentioned, Marathon is an extraction shooter. In these games, players have a time-limit in which they must explore an area, search for loot, and safely extract. Of course, the actual gameplay is a bit more complicated than that.

as a PvPvE game, you'll encounter other players and UESC mechs that are out to kill you, with the former trying to steal your loot. Thankfully, you won't be alone, as you can team up with up to two other members before heading to the surface. However, you can also play solo, if you so desire.

Unlike Arc Raiders, Marathon is also a class-based shooter. Overall, the server slam provides five different Runners (including Rook) for you to play as. Feel free to check out the full list of Runner Shells you can assume control of on Tau Ceti IV.

During the Open test, players can Infil into two zones, Perimeter and Dire Marsh. Furthermore, you'll also be able to accept contracts from five different factions, including NuCaloric, CyberAcme, Traxus, MIDA, and Arachne. During the Playtest, you can begin progressing through early faction levels to access your upgrade tree and improve your character.

Like the Arc Raiders Server Slam, you won't have access to every feature that will be available at launch. This includes:

  • Late-game zones (Outpost and Cryo Archive)
  • Full contract and progression depth for all factions
  • Ranked mode
  • Sixth Runner Shell (Thief)
  • Season 1 and end-game unlock content

Overall, that includes everything about how to play the Marathon Server Slam Open Test on PS5, Xbox Series X|S, and PC. For everyone who decides to hop in on this free adventure, we wish you the best of luck in extracting some sweet rewards.
