Rocketbirds: Hardboiled Chicken is making the jump to Vita in next week’s PlayStation Store update. The portable incarnation has a couple of improvements over the PS3 version – tilting screens, two difficulty settings, ad hoc and online multiplayer, improved graphics and a new end boss. If you already own the PS3 release, you’ll get a discount on the Vita version and two extra co-op characters. Trailer and screens through the break. Rocketbirds: Hardboiled Chicken is also available on PC.
