Stephanie Nunneley of VG24/7 covered the news of the Steam release of PixelJunk Shooter Ultimate, an enhanced collection of both PixelJunk Shooter 1 and 2.  The game was developed by Double Eleven in collaboration with Q-Games and features the same twin stick shooting action mixed with puzzle solving elements the original games had, along with an option to switch between the original and upgraded art styles.
