How to unlock the Dragonslayer - Destroy the ATAC within 1 minute 30 seconds achievement in Killzone 2 - Definitive Guide
The fastest way to defeat him is the following:
-pick up the rocket launcher by the center pillar.
-when the ATAC is hovering above/near a blue capsule, shoot the capsule with your sidearm until it explodes. This will stun the ATAC.
-immediately fire your first rocket shot, and don't miss. You'll have time to fire a second shot and hit him if you do this fast enough.
-after the second hit, the ATAC will begin moving and attacking very quickly again.
-repeat the same strategy with the other capsules. The attack takes 3 hits I believe, but may be more on higher difficulties which I have yet to play at this point.
After a few tries you should definitely be able to do this no problem.
You will find the ATAC in the Salamun Bridge level, Academy Rooftop checkpoint . You can't miss it. As soon as the battle starts, check which side the ATAC moves to. When he is in position over the fence shoot the blue lights with your rifle. The ATAC will get stunned, now quickly run up towards the stairs. there will be a Missile Launcher on the ground (on both sides). Equip it but don't fire. Now press to equip your Pistol, aim down the sight on one of the blue lights. As soon as they regain full strength (full light), shoot it to keep the ATAC in stun-mode. Now take out your Launcher and pop one in him. Don't wait for the reload, just draw your Pistol again. Repeat said move, now reload, draw pistol, fire on the light. Draw Launcher, fire Launcher, draw Pistol etc etc etc. if you run out of missiles there are some on the other side of the platform, just keep the ATAC in stasis the whole time.
If you are having trouble, please note there is a tunnel beneath the roof - you can easily hide in it. This video may be of help (credit Aidan).
