Start a new game on Expert and complete it.

When you die the game will save your death so reloading a earlier checkpoint won't work. At the start of each mission, save your game and copy your save over to a memory stick and if you die, you've got a backup in place.

Refer to the road map for a walkthrough if you're struggling with any missions. Below are my top tips to help your score. After completing the game and receiving your final score, the trophy should unlock but I believe your final score has to be higher than 80%.

• Watch the training videos at the main menu (they really do help).
• At the start of each mission, pick the Stealth load out (or Redding's if you prefer flash bangs).
• Complete secondary objectives.
• Avoid being detected as an intruder and setting off alarms.
• Use to knock out guards and hide their bodies where no one will find them.

Playing on Normal will make this trophy very easy; simply complete the game without using any medkits. For mission 10: Kokubo Sosho you may want to refer to "Not Today".

Start a new game on Normal and complete it to unlock this trophy.

You can pull one guard over a rail in missions 1. Lighthouse & 4. Penthouse.

Warning: video may contain spoilers.

The first mission would be the easiest to do this trophy on, since there are no alarms or cameras to worry about.

When under a pipe, press & again to attach yourself to the pipe and when an enemy is under Sam and you see the dialogue box: “Grab character,” press to do an inverted neck grip.

Warning: video may contain spoilers.

Press to “Use computer” then press again on “Security Access” if the option is available. Mission 3: Bank, has a lot of computers you can hack.

Aim your pistol at an electrical source (e.g. Light bulb) and press to temporarily disable it.

Get out your SC-20K assault rifle and press to switch to the shotgun attachment. This can only be done on the following missions:

7. Battery
8. Seoul
9. Bathouse
10. Kokubo Shosho

(Make sure you pick the right loadout)

Mission 10: Kokubo Shosho, when you go down an escalator, Redding will talk about 3 LTL guards at the bottom. Let them capture Sam and he will wake up inside an interrogation room handcuffed. Picklock the cuffs, then the trophy should unlock when Sam gets up.

Note: If you are going for "Immune" I recommend making a save before being captured otherwise you will have to complete the mission with only a quarter of your health left.

Warning: video may contain spoilers.

Go up to a enemy and use to kill them with your knife. Playing through half of mission 1: Lighthouse and knifing everyone should unlock the trophy.

Mission 1: Lighthouse – Right at the beginning, past the wooden bridge and room full of barrels, you enter another room where you will hear Morgenholt being tortured. Take out the guard(s) and press to cut him down and the trophy should unlock.

Do the opposite of "Dignity and Honor" and don't cut Morgenholt down, trophy should unlock after completing the mission.

Story related can't be missed. Mission 2: Cargo Ship, when you have learned that Lacerda is in the captain's quarters, go down there. After he has complained about bribing an inspector he will go get a drink, this will be your opportunity to assassinate him and unlock the trophy.

Go near a scanner and use your EEV to hack it from a distance. There is 1 retinal scanner in each of the following missions:

3. Bank – Across from the sleeping guard after climbing down the rope.
5. Displace – Near where a guard sits at his desk and opposite the door to the gym-like area.
7. Battery – After taking the lift up you should see a guard and camera to your right and the scanner straight ahead on the right side of a door.
10. Kokubo Shosho – After taking the escalator down, go right down some small steps to find the scanner on the left side of a wall.

Pick a level you are familiar with, get behind a door and use whistle to lure a guard you can see towards the door. Press and select “Bash door” to knock the guard out.

Go up to a computer and press then select “Shutdown pc”. Mission 3: Bank has plenty of computers to switch off.

Switch to thermal vision and kill any enemies using the SC-20K assault rifle while zoomed in. If you do this on mission 1: Lighthouse, the trophy should unlock by the time you get up to the IT Technician guy (by the laptop).

Story related can't be missed. Mission 6: Hokkaido, Milan will have a conversation with his men about the Displace offices being turned over in New York. Kill Milan and the trophy should unlock.

Mission 9: Bathhouse, after disabling the last bomb (and killing the last guard) you will go through a door. After a small struggle with Shetland, you will both hold each other at gunpoint. After he says “you wouldn't shoot an old friend“ prove him wrong and shoot.

Like "Price of Betrayal" but instead, put your pistol away by pressing .

Story related, can't be missed. Mission 10: Kokubo Shosho, after stopping the launch of another North Korea missile you will go and confront Otomo. When he impales himself with a dagger, you will need to take the vent on the floor to your right and go save his life by pressing near him to remove the blade - trophy will unlock when the mission finishes.

Mission 8: Seoul, when you come up to the crash site, go right to the front of the plane and carry the 2 pilots back to the alleyway (watch out for the tank), then go and call in an air strike.

Tip: the walkthrough in the roadmap has a good strategy for dealing with the pilots and tank.

Like "Unsung Hero" but instead leave the pilots and call in the air strike, trophy will unlock when the mission ends.
