I'm sure there are lots of guides but I just got platinum for the game and I though I would do my own version so I hope it helps for those who need it.
First thing, when you press start during the game it says the stunt you are on but this is actually 1 less than you've completed (e.g. stunt 20/21 means you have 1 left to get - if that makes sense)
Secondly, the stunts are easier to get when you play as good as many require shockwaves which make enemies fall slower.
Crush- Kill an enemy by crushing them with an object. You need to shockwave a car towards an enemy - killing them. This is easiest with the good, not upgraded shockwave, when enemies are behind a car. Good spots for this are during the mission where you defend the engineer whose fixing the bridge. At some stage, enemies come out from a side street with lots of cars infront. It can also be got when you are riding the bus to the hospital and during the first train mission where there are cars on the tracks and roads with enemies behind them.
Sticky Bomb - Kill an enemy by fixing a sticky shock grenade to them. Easy; throw a shock grenade at an enemy. It doesn't always stick or hit the enemy so just try it a few times.
Highfall - Kill an enemy by making them fall from a high place, usually over a ledge. Easy; shockwave an enemy over the edge of a high building, facing the side with the longest drop.
Enviro Take Down - Kill an enemy with environmental explosion. Blow a car up when an enemy hides behind it.
Melee Finisher - Kill an enemy with the last hit of 5 hit melee combo. Just keep punching an enemy, to get the 5 hits, do this on stronger enemies (such as on the 3rd island) or by not upgrading the melee move so your hits are weaker.
Air Strike - Kill an enemy with the Lightning Bolt move while Cole is in the air. Climb up a building when an enemy is on the ground, jump off, aim and blast them. This can take a few tries as aiming can be tricky. Also make sure you rapidly kill them and make sure you jump far enough away so cole doesn't grip back onto the building.
Blast & Bolt - Kill an airborne enemy with the standard Lightning Bolt weapon. Shockwave an enemy off a building and shock them as they fall. This is easier with the upgraded good shockwave as enemy don't fall as fast.
Flying Head Shot - Aim carefully, and take out an airborne enemy with a headshot. Shockwave any enemy off a rooftop and use precision to get a headshot while he is in the air. Might take a few tries as the enemies can be in different positions as they fall.
Flying Melee - Kill an airborne enemy with a melee attack. This stunt is very annoying. You can get it by chance when meleeing an enemy especially on the edge of a roof. If cole doesnt kill them he might lunge off the building to hit them again. I got it when killing yellow, trash crabs. Lure one into the path of a car and they get knocked into the air, then hit them.
Unquenchable Thirst - Induction grind and transfer to 4 different grinds without touching anything else. Induction grind along the tall, black power lines in the warren along the canal starting from the train station end. When you jump from one to the other slow your speed by pressing back slightly on the left stick so you dont jump as erraticly.
Premature Detonation - Kill an enemy by making a bomb-equipped kamikaze enemy explode near them. There will be points ingame at which a kamikaze (the guys that blow themselves up trying to kill you) will be around other enemies. Shoot them so they blow up killing the enemy.
Right Back At Ya - Use the Shockwave move to deflect a thrown grenade back at the enemy who threw it. This is the hardest trophy. When you play as hard, enemies throw grenades more so there are more opportunites. Areas where this is easiest are less open areas using the good shockwave. Its very hard to aim the grenade back so dont try it on the flying machine things in the historic district- its impossible. At Alden's Tower however there are two places where you can get it 1) 1/2 way up the tower (near the elevator to bring zeke up) there is a grenade thrower. 2) A spot on the very top of tower where the big battle takes place. During the battle 3 grenade throwers and i think 2 shotgun dustmen spawn in.
Air Sticky Bomb - Kill an airborne enemy by sticking a grenade to them. Shockwave any enemy into the air then stick a shock grenade to them. Just keep trying as getting the grenade to stick can be difficult.
Insult To Injury - Stick a grenade to an enemy, but then kill them with another weapon before it explodes. How i did this i stuck an enemy with a grenade then used precision to take him out. you need to be quick between throwing the grenade and using precision.
Whack A Mole - Kill a Conduit with the Thunder Drop move. When kessler talks to you about 'evolving' during the mission on the third island, you first come across the first big purple conduit. Shoot it until it shrinks and falls down. Then run up to it and thunder drop it until its killed.
Suspended Sentence - Kill an airborne enemy with the Thunderstorm move. Right after you acquire this power youll have to go out and activate 3 above ground transformers. During the third one, enemies spawn right infront of you. Thunderstorm the area which blows up cars aswell, making enemies fly into the air then shocking them. If you dont get it, let yourself get killed and then try again until you get. It shouldn't take more than 4 tries.
Up Close And Personal - Kill 5 Enemies back to back with just the melee. Don’t fire in-between. When you come across a conduit who summons the yellow, trash crabs, let it spawn lots of crabs and melee them back to back.
Crowd Control - Kill 5 Enemies at once. Repeat the above but get away from the conduit so he cant shoot you but making the crabs follow you. Climb up a pole or streetlight so the crabs collect, then throw a grenade. It can also be done using thunderstorm near the end of the game during the 3 transformer task.
Splash And Crash - While in the air, Shock an enemy and then hit the same enemy with the Thunder Drop move. easier when you fall from taller building so you get more time. Just keep trying.
Have A Nice Fall - Kill 3 enemies at once by making them fall from a high place. This stunt may take some time. During the neon mission where you have to destroy the tar things on the roof, there are groups of enemies on the roofs. Hang on the building edge and wait till they collect on one side then shockwave all of them off. You can use multiple shockwaves so they are fall. It took me about 7 times when playing as good on hard.
Ride The Lightning - Kill an enemy with Precision while rail grinding. lots of places to do this, especially when you have completed fewer missions on one island as there are more enemies. Just ride the raillines until you spot an enemy.
Got any more tips for it?
