Killzone 2 Walkthrough

This last stretch of the courtyard is by far the mostly strongly defended. Enemies respawn endlessly, so there's no point in trying to hang back and kill everyone before moving forward. Instead, focus on clearing a temporary path that'll let you progress closer to the palace. As you reach cover that's closer to the palace doors, enemies will be sort of pushed back and will stop spawning further from the entrance.

Take special care to target the turret gunners as you get close enough to them, and try to stay on the far sides of the courtyard—left or right—so that your back is always against a wall instead of facing more enemies. You want to keep a full stock of grenades and ammo for after the courtyard firefight, but there's plenty of ammo that you can gather after the fact. Unload at will to make your way to the palace. Before stepping inside the palace, move into the empty turret gunner's arcade to the left of the palace entrance. In the back corner is the final emblem.

Autarch's Sanctum

Once you've infiltrated the palace, you'll have a quiet run through the first foyer and into the main sanctum with a massive statue in the center. Walk across the room until you trigger a cut scene that leaves you to defend yourself against Radec's men. For now, you're trapped on the lower floor so find some cover near the entrance to the sanctum and drop the enemies that spawn around you.

Radec will warp around invisibly on the level above you, but you can't kill him yet. If you start taking fire from an invisible source, it's likely Radec. And while you can't kill Radec yet, you can shoot him to interrupt his spray. Listen for the tell-tale sound of doors opening—cha-chink, cha-chink, cha-chink—that'll let you know that more enemies are about to enter the room. Look all around you to make sure you don't get flanked, as some enemies will spawn on the balcony behind you and rappel down to the ground floor.

Eventually, the Helghast will get desperate enough that they open the gates at the base of the stairways on either side of the sanctum. Make your way upstairs and kill the flame throwers at the back of the balconies to take care of an objective. Move to the top of the stairs on the right side of the sanctum—right assuming you're facing the end of the massive room where Radec and his cronies originally came from.
