Dear Thunder Spikers,
It's true that we don't release updates much frequently, but when we make one we make it BIG. In this update we added Achievements, a necessary split-mode for Single Match (each player now controls its half of the UI), improvements to the Leaderboards screen and a tons of UI polishing.
But most of all, we released a brand-new Co-op mode! This mode allows up to four players to play in Single Match (2 vs 2), and allows a friend to join your games against AI in Arcade or Career modes.
For the latter two modes, you will need to setup the Co-op in the pause screen, clicking ESC or Start on the pad. There, you will find a new "Co-op" button that will open this popup: 
Just click the action button on the pad or keyboard to join the game and enable co-op. Click any button on the controller first, if it doesn't appear in the list.
We can't wait to see your videos and read your feedbacks about the co-op. We think that co-op brings a completely new way of playing the game.
Here is the complete changelog for this update, many fixes were made to the UI that is now much more stable and polished (mostly in the team creation screens and the career in general). The localizations had many problems that should be fixed with this update.
