The PlayStation Vita edition of the game allows for cross-platform play with users of the Windows edition of the game, by allowing characters to be synced between copies. The game experience is modified slightly, by reducing the number of enemies that spawn in instanced areas, and reducing the size/complexity of instanced area textures/models. As well, the PlayStation Vita's touch controls are fully utilized for the game interface.
The Special Package Vita retail version includes a number of unique in-game customization options, including costumes and a special Mag device. Included is a set of stickers to decorate your PS Vita console, or for collecting.
