PlayStation Vita FPS Killzone: Mercenary is a full Killzone experience, not a shrunk down version of the PS3 shooter Killzone 3, game director Piers Jackson has told the PlayStation Blog.

Speaking about making the transition from PS3 to PS Vita, Jackson said: "In some regards we've tried not to shrink it at all - we've tried to get a full Killzone experience running on PS Vita. The system is incredibly powerful - we've got graphics that are comparable to Killzone 3 running on a handheld."

Regarding getting the Killzone engine - made for PS3 - up and running on the Vita, he added: "It's optimised in a lot of locations but the core AI system is based precisely on Killzone 3. We've had to replace a few of the audio and rendering systems but the back-end leading into them is pure Killzone engine architecture. We've also got certain things in the renderer that are unique to our system - we've added reflection mapping on the floor and particle systems can actually be lit as well.

"There may be a few areas we've had to tone back a bit, but we're pretty convinced that we've come up with something that touches most of the technical features from the main Killzone engine."

Given what we've seen of the game in the trailer you'd be hard-pressed to argue with Jackson's comments.

The game's set for release September 18, one day after Grand Theft Auto 5.
