Summary: For the price, three decent shooters are a good buy. The first game is dated of course (it was a PS2 release originally) but it wasn't too bad and it set up the story for the rest of the games. The second game focused on rebalancing but also removed secondary fire. Things like the ISA assault rifle was given accuracy (something sorely missing from the first game) and more common ammo drops, while the Helghast LMG was crippled and only effective at point blank range.
Summary: Kz1 was ok, I understand it was upgrade from ps2 but not a good game. Kz2 was better but still just ok. I stopped playing kz1 and kz2 within a few hours for both games. Kz3 great gameplay and the graphics are much better.
Graphics are incredible, but story line is lacking.

Summary: Even back to the very fist Killzone, the graphics were pretty good considering its age. But the second and third take the cake for graphics and design. But the storyboard seems to need a bit of work.
Summary: The Killzone trilogy sets the stage for the first-person shooting action in a variety of war-torn environments. The guns and grenades let you blast away at the enemy with glee, but the game is not a push over. The enemy computer combatants position and cover well. Online multiplayer modes are included so that you can mix it up with human combatants and if you are a FPS fan you'll find free DLC multiplayer maps.
Summary: Since I was so surprisingly engrossed in Killzone Mercenary, I decided to pick up the Killzone Trilogy. If this was a novel series, you'd want to start your consumption from the beginning of the series. But video games, unlike movies, improve dramatically over time, so you want to start in the inverse order with Killzone 3 first. Basically, the game is setup to have an arena of play, followed by a cut-scene, and followed by another arena.
Summary: Back in the early 2000s, Bungie's console sci-fi first person shooter "Halo" was pretty much the benchmark for the genre on consoles. Halo's slick controls and graphically impressive presentation helped keep the Xbox's head above water long enough for it to garner a decent amount of publisher support over time.
Summary: I had never played any of the KZ games before purchasing this trilogy, so my opinion of it is colored by having first experienced other shooters (like COD and Halo). I'll also mention that my review focuses on the campaigns, as the online multiplayer just isn't my style. Killzone 1 was a very simple, no-frills game that was fun but with telltale signs of its age.
