One of the biggest PC game launches this year is already suffering from server issues that are stopping some players being able to play the game at all.The problem is reportedly down to Ubisoft's Uplay service, which is required to play the game single or multiplayer. Ubisoft have tweeted out to players: “We’re very sorry for the server issues affecting Far Cry 3 on PC and are working as fast as possible to restore the service. “Ubisoft had also released a day-one patch for the game mentioning it as a “critical update that needs to be installed in order to benefit from an optimal game experience" Several gaming websites are advising players to switch the game into Offline mode, which should hopefully allow them to move on with the single player campaign while they wait for multiplayer to become active again.
