Free 30 Day Trial & Continued Access

.Fallback Initiated

XOOMHey everyone, as we've been announcing through our communication channels the release of was a pretty tall order and some things snuck through requiring us to fallback to in an effort to regain stability over server and client performance. Worry not, we're going to take a short breather and then get right back to rolling out those features in smaller chunks so we can isolate features in a controlled manner. CRS always works to ensure we release solid updates and for a long time now things have been smooth. A lot has been learned and we appreciate your patience and understanding on all of this, and we apologize for its impact on you.

Campaign 182 will be restarted today at approximately 1:30PM Server Time (PST).


  1. Manually uninstall version (or any version of the game currently installed)
  2. Download version, downloads page here
  3. Install and standby for campaign launch

Steam downloads should be updating automatically. is Coming today!

XOOMToday at 4PM server time (PST) the Campaign server will be brought offline for the release of WWII Online Version (readme). Aarschot and Tienen will need to be disabled due to uncapturable AB's (we're working on a hotfix for that later). This means that the new Campaign will start tomorrow with the update in it. Be sure to review the readme and get familiar with everything coming in this patch because it's a MONSTER update, loaded with new features and fixes. Once again, thanks for your patience while CRS has been working literally around the clock to get this to you.
