Arc Raiders Server Slam hits 189k concurrent on Steam before Oct 30

Embark Studios’ final open test of Arc Raiders drew an estimated peak of nearly 190,000 concurrent players on Steam as the Server Slam weekend wrapped up ahead of the game’s full release on October 30, 2025. The three‑day stress test, which ran from October 17 to October 19 across PC (Steam and Epic), PlayStation 5 and Xbox Series X|S, was open to all and aimed to exercise matchmaking and backend systems before launch.

According to SteamDB, the playtest reached a peak of 189,668 concurrent Steam players. The Server Slam was intended as a capacity and stability check and featured a limited slice of the full game, centered on the Dam Battlegrounds map and a small selection of progression, crafting and quest systems. Embark said the event required no access codes and offered a cosmetic reward, the Server Slammer backpack, to participants when the full game releases. Progress made during the test will not carry over to the retail launch, and players must use the same Embark ID and confirm their email to claim the cosmetic. The event also had a minimum age requirement of 16 for participants.

The test ended on October 19 at 8 a.m. Pacific, 11 a.m. Eastern and 4 p.m. British Summer...
