We will be taking our PS4 game servers offline starting at 9:00 AM CDT while we promote Patch 3 to the live servers. Maintenance is expected to end at 3:00 PM CDT. During this time, players will be unable to log-in. Get up-to-date info as maintenance progresses in this thread or on our GreyBoxCS twitter feed.
