Medal of Honor: Warfighter has only been released for roughly 10 hours, but EA has already released a massive day-one patch that addresses both the multiplayer and the single-player portion of the game.
Most of the path fixes minor issues, but there are some much bigger issues that were fixed as well. EA has also held back on review copies to the press due to these glaring issues. Some of the more notable fixes include: players being able to join private matches without an invite as well as having everyone in the match being able to listen to your team voice chat.
