In October, Embark specifically conducted server testing, trying to prepare for the release.
Players are massively complaining about the server issues with ARC Raiders. Getting into a match is extremely problematic, but even if it does happen, there is a high probability that the connection will be interrupted at the most inopportune moment.
The developers from Embark have not officially commented on the server issue yet, but it is likely that the studio will fix everything in the near future.
ARC Raiders is available on PC, PS5, and Xbox Series X|S.
