Killzone 2 Walkthrough

Very quickly turn around and run up either set of stairs at the far end of the room, moving through automatic doors at the top of the stairs to reach the upper level of the massive theater beyond. The theater is soon to be flooded with Helghast on both the upper and lower levels. Use your shotgun to rush the Helghast enemies on the upper level and drop them with the quickness. Enemies with RPGs will show up and you'll want to take care of them quickly.

With the theater cleared, look for another emblem overhanging the door that exits the room. Wait for Rico to bust the door open and then follow the hall and stairs beyond, moving upstairs and through another automatic door to reach Radec's office. On Radec's desk in the center of the office is a bit of intel to grab.

Academy Rooftop

A cut scene will soon take over that leaves you on the rooftop of the academy, left to defend yourself against a flying ATAC. Look to the left for a rocket launcher, grab it, and then turn 180 degrees to find a stairway on the outside of the rooftop platform that leads down to a lower level of the rooftop.

There's a hall to the left of the bottom of the stairs that provides pretty good cover from which to launch your assault on the ATAC. Note the rows of glowing-blue electricity coils on either side of the rooftop. Shoot one of the coils with your pistol and the entire line will ignite, and if the ATAC is within range the spark will stun the hovering craft long enough that you can hit it with two rounds from your RPG.

You'll need to hit the ATAC four times with RPG shots. There's plenty of ammo littered about the rooftops, and if you're careful with your shots you should never have to leave the safety of the hallway to restock. Successfully bring down the ATAC and you'll move to the next stage.
