Easiest done in Prologue (training doesn't count) try pressing (L2) right before you land from a high distance. Faith will do a skill roll and won’t take any damage.
Be careful: when dropping down from the vents (first encounter with enemies) make a skill roll! Otherwise you'll get hit and this counts as a heavy landing.

Easiest done in Prologue. There are 2 enemies that you'll encounter. At the first enemy, try jumping (L1) and press (R2) (kicking) at the right moment so that you body smash him to the ground.
(This will get you the Secret trophy ''Hey it's-a-me!'') Now move to the left to avoid the second enemy's gunfire. Activate Slow motion with (Square) and disarm him with (Triangle).

Just melee opponents (R2) or disarm (Triangle) them and throw away there weapon with (Triangle). Never press (R2) when wielding a weapon and you’ll be fine.

When an enemy is standing next to a wall, approach the wall and press (L1) to wallrun. When close to the enemy, press (R2) and Faith will kick the enemy.

Run towards an enemy and when he's trying to smash you with his weapon, press Triangle when the weapon turns red and you will disarm him. This is easier when you got slow motion (press Square to activate). You get this trophy by playing through the story mode.
You can use the tactic described in the ''Tango Down'' trophy.

When engaging an enemy, hit (R2) to melee. A police officer takes about 2-3 hits and an armored Swat police officer about 4-5 hits.
Try jumping and kicking (L1 + R2) or sliding and kicking (L2 + R2) for easy hits. You can only kill people that are red.
Easy done in the metro level. There is a part where you have to fight 2 police officers and 4 swat members.
Try knocking out as much as you can and die. You respawn with all the enemies back to life. Just rinse and repeat. You get this easily if you just play through the story mode but you can use this method if you skip all the enemies.

The DLC map you'll get this on is Velocity. Follow the video (thank you to TheFlyingToaster).

This one is done on the Flow DLC map. Again, follow the video (thank you to TheFlyingToaster).

This move is done on the DLC map Actino Rise. Follow the video (thank you to TheFlyingToaster).

Complete the 9 and last chapter called The Shard on any difficulty.

Same as ''Baby Steps'' only 35 stars.

In Chapter 6, checkpoint D, after the sequence about Project Ikarus, you need to escape from the guys who came in the elevator. As soon you have control of Faith, just run in circles around the base you need to climb. The area is large enough to maintain speed. You need to maintain 30 seconds in full speed. Try not to do edgy corners, try to stay in the same direction, doing the corners softly. Stop running when you think you hit 30 seconds. The trophy will pop up if you stop.

Easily done in Prologue. Start checkpoint A and the first fence you jump (L1) over you can coil up and then carry on holding (L2) down and slide under the pipes.

Run towards a wall and press (L1) at the right moment, then press (R1) and (L1) again and speedvault. A speedvault is when you hurdle a mid-height obstacle perfectly, which makes you gain speed. To do this press (L1) to vault an object that's in your path.
Easy to do in the tutorial: When crossed the pipe you see a small building. Instead of climbing on it, wallrun the wall on the right and jump on the ledge. You'll have more than enough height to do a speedvault.

Press (L1) to start wallrunning next to a wall, then press (R1) to turn, (L1) again to jump towards an edge. Press (R1) when climbing on the wall followed by (L1) one more time and this trophy will pop up.
Done in Prologue: The 2 buildings you're after is the one where you have to cross the pipe and the one right next to it, run up towards the left wall and start a wallrun, quickly do a 180, jump again, another 180 then jump and you should be on top of the pipe building and 30 points better off.

Press (L1) to start wallrunning and (L1) again to jump. Press (L2) when in the air to coil over an obstacle and finally (L2) again to roll and trophy unlocked. A good place to do this is Playground two in time trial mode. Go to the second checkpoint and look right of you for an orange stair. Now go a little bit forward (keeping the stair right) and you'll see some wood right next to the building left of you. In front of that wood there's a fence with a wire. Now go back a bit, make a run to the plank, on the end of the plank press (L1) and jump toward the building (you'll be wallrunning now), when almost at the fence press (L1) again (timing is important) and quickly press (L2) and (L2) again to skill roll.

Easiest done on easy difficulty. Just melee opponents (R2) or disarm (Triangle) them. When disarmed throw away their weapon with (Triangle). Note that the trophy says never shoot an enemy so you can shoot a gun but don't hit an enemy. If you want to be sure, just never press (R2) when wielding a weapon and you’ll be fine. To check your progress press (Select) and if the text ''So far, you have not fired a shot at anyone'' appears at the top right then you're doing good.

Play the DLC map Kinetic for this trophy. Follow the video (thank you to TheFlyingToaster).

Depending on how many stars you got on the original maps, this either won't take very long or you'll have to devote a good amount of time to it. Start by going through the new maps and get as many stars as you can. See the videos listed with the Superstar trophy for help with the DLC maps. Also, remember to download ghost times for shortcuts to improve your times.

Hard difficulty will unlock when you complete chapter 9 on any difficulty. On hard difficulty you’ll die faster from damages and have no runnervision (no red objects).
TIP: When attacking enemyies, try to lure one and disarm him with Triangle. With his weapon you can easily shoot (R2) his teammates. It's very hard to fight them with melee and going for the "Test of Faith" trophy.
*Some people are having trouble with this one. Start a new game on hard and not from chapter select to be sure*

Every level has 3 hidden bags in it. Look for runnermarks. When you spot one there’s a bag nearby. Use this video guide (Click) for the locations.

Same as ''Baby Steps'' only 50 stars.

This is going to take a bit of time. You'll want to hit 3 stars on as many of the DLC maps as possible, and you'll most likely have to go back to the original maps and improve some of those scores as well. The following videos show how to get 3 stars on each of the DLC levels. Also, remember to download ghost times for shortcuts to improve your times.
