Just so you know, yes, there is a Polish magazine that has our exact same name. And yes, it's just a coincidence.
Anyway, according to Examiner.com citing the aforementioned magazine, PSX Extreme, the upcoming Killzone: Mercenary for the PlayStation Vita "makes use of nearly the same engine" as the one used in Killzone 3 for the PS3.
Supposedly, developer Guerrilla Games has "added some new gimmicks" to the existing engine (which likely included touchscreen commands) and graphically, the game impresses. That probably won't surprise anyone who's familiar with the franchise. The source goes so far as to say that Mercenary looks even better than Uncharted: Golden Abyss , which is certainly a big-time visual tour de force for the Vita. Lastly, in terms of frame rate, it's apparently quite stable even when it's "highly active" and PSX Extreme (again, not us) labels the title as a "portable Killzone 3 ." Well, we certainly hope so.
Expect to see some official information very soon…
