I noticed on the European Playstation Blog that Battle Worlds: Kronos was released today on the European Playstation Store.
However, I did not find it under the new releases in the store; I had to manually search for BATTLE WORLDS in order to find it.
Just that you know, that you might give Sony Europe a call, that your game is not placed under New Releases, but it is available in the store (people only have to look manually for it).
Because it would be a shame that you miss the opportunity for your game to be sold because it has been placed somewhere in a quiet corner...
