Killzone 2

Radec is difficult, but not impossible to kill, especially if you are attempting to get the "Demonslayer" trophy for killing him in twenty minutes. Do not worry about him until you get the cinematic where he says "I guess you want to make it personal!" In the beginning he sends hordes of Helgast troops at you. Just dig in and kill them all. You will be on the ground floor for about three waves of troops. Then the doors on the side will open, allowing you to get to the balcony. Note: Ammunition is limited on the balcony. Make your shots count. When you go up onto the balcony, there are two flamethrower Helagst waiting. Afterwards there will be two waves of infantry then a mixed group of infantry and knife wielding Helgast officers. Watch out, because when you are on the balcony they will come up from both sides. Take care of them first, then focus on the floor troops. After this wave you are greeted with RPG troops on the far wall of the room. Take them out, then go back to the floor troops. After about six waves you get another cinematic of Radec. You are now back on the ground level. He now phases in and out of invisibility, and shows up beside you and tries to knife you. Keep moving and shooting at him as he shows himself. After hitting him enough times, he retreats to the stairs in front of you. Keep shooting, and when he goes down the battle is over.

After he makes the comment about "making it personal", there will be waves of troops that keep appearing. There is no real strategy here other than "run and gun". When it gets down to just you and Radec, and he keeps turning invisible, stock up on ammunition (rifle recommended). Go up to the balcony and put your back in a corner. Radec will not be able to sneak up on you. You only have to cover left and right. You will hear him appear and see a flash of light to indicate which direction he is coming from. Occasionally he will appear on the ground floor. Peek over the rail and shoot him a few times, then get back to the corner. After a short while he will appear on the stairs. Finish him off and you will have defeated him.

Select "Create Game" and the Suljeva Cliffside map. Select "Body Count" for the match type and set the kill limit to "25", match time to "30 minutes", and max players to "2". Place one A.I. bot on the Helghast faction and set the bot difficulty to "Recruit".

When you cross the Salamun Bridge and lower it for the rest of your squad to cross, take the sniper rifle on the weapons rack. Walk out the door, but do not advance further down the bridge. Above the road is a turret with a gunner. Shoot him in the head and wait a few seconds. Someone will replace him. Keep shooting them in the head until you are awarded the trophy.

The helmets that you have to shoot off the Helghasts do not have to be on live targets. Simply shoot them off the corpses to build the count towards the trophy.

If you die while attempting the Untouchable Trophy, fret not. There's no need to restart the entire game, just press pause and restart the level. Your death count will be reset to 0.
