That's one of them, anyway. It'll be $11.99 for Plus users when it comes out tomorrow, and $14.99 for everyone else. Tokyo Jungle will be subject to the same discount, while Starhawk's single-player component will be subject to an even more significant discount.
Along with the single-player DLC, the Starhawk campaign is free on PSN for Plus members. Now you know what to play next after your surprise downloads of Borderlands, Scott Pilgrim, and Double Dragon Neon.
