Metal Gear Rising: Revengeance‘s always-online PC problems have been fixed, according to a couple of tweets this morning from Kojima Productions’ Steve Key. A Konami representative also confirmed to Kotaku that the issue has been resolved. New downloads should work fine, though already-affected users will probably have to re-download the game and Konami now says that the fix should immediately go into effect, with a Steam restart.
