Sure, the original Killzone may have failed to be the "Halo-killer" it was proclaimed to be, but after a painfully long time in development (the sequel was supposed to be a PS3 launch title), Guerilla Games finally delivered a first-person shooter that pushed its console to its boundaries, mostly in terms of graphics. Even stunningly polished shooters like Call of Duty 4: Modern Warfare lacked the level of detail displayed in Killzone 2's bleak, post-apocalyptic wastelands and war-scorched cities. As soon as you boot up Guerilla's killer FPS sequel, there's no ignoring the mind-blowing lengths that the team behind the game has gone to, bringing the battlefield to life. Killzone 2 remains to be one of the best next-gen shooters, and is one PS3 game that's recommended for those who can appreciate its gritty science-fiction spin on the genre.
