The Knowledge
Find all collectibles in the campaign
There are a total of 98 Collectibles in Killzone Shadow Fall. 35 Audio Logs, 19 Dossiers, 9 Newspapers, 35 Comic Books. Finding all of them will earn you a silver trophy “The Knowledge”.

In the main menu, all collectibles are listed by their name. You can see exactly which ones you have found and which ones are still missing. Chapter select does also provide an extra progress tracker. It shows how many collectibles you have found in each chapter.
If you miss a collectible by accident, you can jump to a specific section right away. The section is shown in the top left corner of the video and can be started via chapter select. You won’t have to replay the entire chapter if you miss something.

However, after picking up one of the collectibles, you have to reach the next section to make it count (except for the Audio Logs, they are saved immediately).

FULL PLAYLIST

Deniable
In ‘The Shadow’, operate without raising an alarm or disabling the security mainframe
Chapter 2 – Section “You have the Intel?”
In the second chapter are 4 alarm systems. They are small, red consoles. Enemies will activate them if they spot you to call in reinforcements. For this trophy, you must prevent that they activate any of these consoles. The best way to do this is by hacking the alarm systems with the OWL. Press L1 while aiming at a console to hack it. After that, enemies can no longer use it and you are safe.
Do this to all 4 consoles and complete the main objectives in the “You have the Intel?” section to unlock the trophy.
Also be sure not to hack the security mainframe. That’s the console on the second floor of the radio tower (last objective, where #4 is in the video). Hacking it will void the trophy. If you trigger an alarm, just restart the checkpoint and deactivate it next time.

Outmaneuvered
In singleplayer, kill 5 Helghast with gunfire while ziplining
Chapter 2 – Section “You have the Intel?”
The best place to get zipline kills is the second chapter. You can start working on this as soon as the “You have the Intel?” section starts. Select the zipline ability for the OWL and press L1 to use it. You must be standing at an elevated position to use the zipline. Just keep firing at enemies while using the zipline until you have 5 kills in total. You could easily do 15 zipline kills in this chapter. Just let the enemies activate the alarm, go to an elevated position, kill the reinforcements using the zipline and repeat. Many enemies are just standing around at one spot, so they are easy targets.
You don’t have to do this in one run. You can do 3 kills on your first playthrough, then do the remaining 2 the next time. However, restarting the checkpoint or section will reset your kills, so farming this via restarting the checkpoint will not work.

Outgunned
In singleplayer, kill 6 Helghast with headshots within a single adrenaline rush
Chapter 5 – Section “Make Him Pay”
A great place to do this is halfway through the fifth chapter. You will come to an area that looks like a little marketplace. Lots of enemies will attack at once, more than at any other point of the story. You really can’t miss this, it’s quite a big fight.
Quickly take out the first couple of enemies, then use the OWL to stun a big group. Walk up to them and press ← to activate the adrenaline. Adrenaline can be picked up at the checkpoint before this fight. It will regenerate your health immediately and slow down time. To slow down time you need to aim using L2. Try to get really close to the enemies, so it’s easier to get headshots. Your standard weapon is fine to do this.

Outsmarted
In singleplayer, get a quadruple kill with a single Frag Grenade
Chapter 5 – Section “Make Him Pay”
A great place to do this is halfway through the fifth chapter. You will come to an area that looks like a little marketplace. Lots of enemies will attack at once, more than at any other point of the story. You really can’t miss this, it’s quite a big fight.
Quickly throw a grenade when you see the big group of enemies. You can cook the grenade by holding down R2. That way, they won’t have any chance to take cover before the grenade explodes.

New Shadow
In ‘The Savior’, complete the mission without being spotted
Chapter 10 – Section “Shadow Fall”
To unlock this trophy, you have to complete the entire last chapter without being noticed by enemies. You can activate the stealth suit by pressing ↓ on the D-Pad. It will render you invisible for an unlimited time, as long as you don’t take damage or fire your weapon. Keep distance to enemies and civilians. If they spot you, restart the checkpoint immediately. Once you go outside, don’t kill anyone at all. Someone would eventually find the corpse and guards will come looking for you. So stay as far away from enemies as possible and keep your stealth suit turned on.

Violence is the answer?
In ‘The Savior’, kill 20 soldiers and still complete the mission
Chapter 10 – Section “Shadow Fall”
For this hidden trophy, you need to kill as many enemies in the last chapter as you can. The problem with this is, that you have a limited period of time and that’s what makes this trophy a little harder. After entering the outside area you will only have 3 minutes and 30 seconds to complete the mission. There are 5 enemies in the building where the mission starts. So you still have to kill 15 enemies outside. Make sure you set the difficulty to easy! Look for a position that is easy to defend, but keeps most enemies in your line of sight. The platform where you pick up the sniper rifle (mission objective) is a great spot. You can shoot through the hole in the floor to hit enemies below. Most enemies will move towards your position, so you just need to defend yourself. By holding down → on the D-Pad, you can highlight nearby enemies.
The trophy pops when the credits start rolling.
