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.
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.
This means that you can no longer play online with PES 2015 after that date.
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.
