Update, according to the UGO Gameblog, one of the control settings is very simmilar to Call of Duty 4, however the couch button has remained R2, which seems weird.

So I just finished the Killzone 2 Demo. The following was my though process as I played the game.
1. Starting the demo – “Holy shit the graphics are lovely”
2. Taking my first step, and killing my first Helgan – “Holy shit these controls are terrible, how am I not dead”
3. Trying to change the controller setup – “Why do none of these control methods make sense”
4. Trying to find the button mapping for the controller – “wait, I can’t change each button to something else?”
5. Finishing the demo – “This looks so good but if only I could actually play”
6. Opening up Call of Duty 5 – “Thank god you have a intuitive control system.”

Seriously, I don’t know what the developers were thinking when they decided it would take holding L2 to lock onto some cover, the left stick upwards to peek over the cover, Holding R3 in to aim (whilst moving to actually move your sight) and R1 to fire.
That’s 4 buttons to preform a simple action.
As opposed to pushing X to duck behind something, pushing X again to stand, Holding L1 to aim, and Pushing R1 to fire.

Don’t get me wrong, this game looks beautiful but there is no way I’m going to shell out money for something that is a chore to play.

ps. I regret playing World of Warcraft.

I got my PS3 on the basis, that Metal Gear Solid 4 would be the most amazing game experience ever created, and two an extent it was – It finished of the series well, and tied up many of the loose ends in the story. It had nice graphics, and brilliant MGS style gameplay. However after finishing the game some big things stood out to me as drawbacks.
The gameplay that was put into the game was much more action based than the original metal gear.
On my first play though I noticed that it was easier and quicker to shoot your way though the game in FPS mode rather than sneak around. Another drawback was the extremely long load time, although at the start of each chapter of the game the disc mentioned “installing” when you went to replay another chapter it would have to “install” again.

After purchasing Metal Hear Solid I became addicted to Call of Duty 4, and then Later Call of Duty 5, both of which were great games, albeit the terrible character models in Call of Duty 5 (fuck treyarch you’re damn lucky you put Nacht der untoten in.)

Being a big fan of Killzone, Great story, Great Characters.
The gameplay was also really good – Possibly the first FPS I played that allowed you to “Stealth Kill” enemies when you had not been detected.
It had it’s bugs, and the multiplayer was quite poor (3 maps, what were they thinking)
If you haven’t seen or played Killzone 1, take a look below at the clips.

Killzone 1 Introduction

Introduction of heavy weapons specialist Rico Velasquez

After reading the article and watching the video below I was pretty much in the mode for Killzone 2
The graphics look exceptional, the gameplay however looks slightly lacking – perhaps worth a rent before you decide to buy it.
However if it turns out this is another fantastic game?
I’ll be finally glad I brought my PS3.
