World War 2 RTS Steel Division 2 has been delayed, but only by a month. Instead of launching on April 4, it will appear on May 2. Developer Eugen Systems says it's to make room for an extended beta and to allow the team to make some final touches based on player feedback. 

The beta—only available if you've preordered, I'm afraid—will kick off on March 27 and run for 48 hours. Beta testers will be able to check out different game modes in singleplayer and multiplayer, including the defence-focused Breakthrough mode and the more aggressive Conquest mode.
