Sony Computer Entertainment and developer Pixelopus have announced that Entwined is releasing today for PS3 and PS Vita.
The game is currently available for PS4. Here is what the developer had to say:
We’re very proud of both the PS3 and PS Vita entries and have put a lot of love and care into them. They both contain all of the content found in the PS4 version, and because they are cross buy it means that if you already bought the PS4 version you will have immediate access to the other two versions for free! Not only that, but Entwined is also cross save, meaning that you can play while away from home on Vita and your progress will automatically update on your PS3/ PS4 versions of the game.
