This patch includes some important fixes:

Code fixes

• DLCs are now properly unlocked for everyone. All content is available, including Operations, maps, and the Japanese faction
• Saves and replays created before the re-release are no longer shown in-game to prevent crashes. If you want to load them, use the compatibility branch in R.U.S.E. Steam options: Properties > Betas > Compat branch.
• Xbox button no longer appear when using the Steam overlay on PC.
