Call of Duty 4: Modern Warfare Remastered servers appear to be live at the moment. This may have been done on purpose to tease players for the upcoming official release on November 4th, or it could just be a mistake.
Either way, players on PS4 can now play online multiplayer and rank up. The servers run pretty smooth so far and the game really feels just like the original Call of Duty 4 thankfully. Whether player rankings will be reset or kept for the full release is yet to be determined but for now it's just great to be playing the game early.
When you load up the game the multiplayer portion should be unlocked, if not try restarting your game.
Upon loading into multiplayer you'll be welcomed with this message.
