"If there's one thing that there was a ton of at this year's E3, it was shooters. While most of them—specifically Gears of War 2, Resistance 2, SOCOM, and even the single-player of Killzone 2—felt improved but familiar (and in a sense less exciting), the multiplayer of Killzone 2 was incredibly surprising. Though it wasn't playable on the floor, I had a chance to sit in with Sony and Guerrilla in a closed-door preview of the multiplayer side of the game and what I saw impressed me."
They also thought the game was generic at first but when Guerrilla started explaiing Multiplayer,this is what they said:
"Despite the few little differences announced early in the presentation, there was a certain feeling in the room that was somewhat "been there, done that" about the whole thing. Once the devs started talking about the game's class system, though, that changed. Surprisingly, Killzone 2 has managed to innovate in a way that I think is genuinely unique: the game meshes the awesome archetypal job class structure of Team Fortress 2 with the ability to equip a sub-job like in Final Fantasy XI."
final word:
"I walked into my Killzone 2 meeting skeptical but walked out impressed. If Guerrilla can pull all of this off with the same, uncompromising graphics engine from the single-player experience—something the company made explicitly clear that it was doing—then the PlayStation 3 may just have its be-all, end-all multiplayer shooter for 2009."
