What to expect in the Marathon Server Slam Open test

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

as a PvPvE game, you will encounter other players and UESC mechs who want to kill you, and the former try to steal your loot. Luckily, you won’t be alone, as you can team up with two other members before heading to the surface. However, you can also play solo if you want.

Unlike Arc Raiders, Marathon is also a class-based shooter. In total, the slam server provides five different Runners (including the rook) that you can play as. Feel free to unsubscribe full list of Runner Shells you can take control of Tau Ceti IV.
