The PSN release is a direct port of the original game, so no HD, trophies or any other modern doodads, just shooting, space-nazis and as much gray as your eyes can handle. It's being published as part of Sony's "Only on PSN" program, and will cost you $10.

Compared to its successful sequels the original Killzone is a mixed bag. It was subject to a ridiculous amount of hype, with many publications touting it as a "Halo Killer," and, as you'd expect, the game had a great deal of trouble living up to expectations. The game's design, which bore more than a passing resemblance to Mamoru Oshii's work in theKerberos Saga, was great, but the game's performance issues and very limited colour palette didn't impress reviewers at the time.

That being said, the underlying shooting mechanics are solid, the back-and-forth banter between the characters was occasionally funny, and if you're interested in the Killzone universe, then this is a no-brainer. Providing this port does away with the original's frame-rate issues then it's certainly worth your ten bucks.
