Barely two years after its initial release, Konami will be shutting down the servers and online functionality for PES 2015 on August 25 this year. This means that you can no longer play online with PES 2015 after that date.
It also means that all of your myClub coins or GP within the game will be invalidated at the same time as the termination of Online service. If you still have left myClub coins or GP, you need to get on it and spend them now, before August 25, or they will all end up going to waste.
It is unclear why exactly Konami are terminating online services of the game so early- especially since their primary competitor, FIFA, keeps its online services up and active for so long. It makes it harder for PES to make a compelling case for itself to the average consumer- and with PES 2017 announced for later this year, fans will undoubtedly be wary of spending $60 on a game that could be dead in less than two years, over a game that is probably going to have a vibrant online community for years to come.
