Konami has released an update for the Xbox 360 version of PES 2014 which it says should restore full online functionality to the game.
Some Xbox 360 players have been unable to enjoy the game's multiplayer offering since the football title released on September 20.
Konami said today that the new PES 2014 update, which can automatically installed from within the game, "delivers an online mode and Master League Online service, and also rectifies previous issues with updating the game via Konami data-packs".
It added: "Konami is extremely grateful for the patience and understanding shown by PES 2014 users affected by the issues."
The publisher said that a full 11 versus 11 online mode is currently in beta and will be released in the coming weeks.
A new data pack featuring over 800 player face updates, updated rosters and improvements based on user feedback will be released in November.
"Further DLC updates created to bolster the performance of the acclaimed football title will also be announced shortly," Konami said.
In CVG's PES 2014 review, we said: "Despite its clear issues, PES 2014 remains a worthwhile upgrade to the series, with all-round improved gameplay and a roster of well built modes. Master League remains as deep as ever, now allowing you to manage a national team. Become a Legend returns too, accompanied by a whole host of new leagues and competitions."
