Killzone 2 is a game set in the near future on the planet of Helghan. The premise of the story is that the ISA have gotten tired of the Helghast abuse, and go to their planet to fight it and kill their leader.
The singly player in this game is very fun and challenging. You encounter various types of enemies with different guns and abilities, as well as very different enviornments to play in. The graphics of Killzone 2 are exceptional. By far, Killzone 2 is the most graphically intense game available for any platform.
The multiplayer is where this game really shines. Spanning over seven classes, the game allows you to rank up while unlocking different abilities and weapons. Each class has their own perks and downsides. For example, the Scout has invisibility while you are sniping, however is very limited at short range. The standard soldier can use almost any weapon for any class, however has no secondaty ability. The mutliplayer is pretty balanced, and always full of action. 32 player games, spanning over 6+ maps means there is always a game to play.
By far, this is the best FPS I have ever played, new or old. This game is NOT one to miss.
