One Man Army
Kill 25 enemies while being dragged from the restaurant, without dying or restarting checkpoint.
This is story-related and can only be done in Chapter 1 – Dinner Out.
You can come back here via chapter select after beating the story or by starting a new game.
Once you get your gun two enemies will run towards you (slightly to your right). Kill at least one of them. After being dragged for a couple seconds you will have to fight some enemies to your left. Don’t kill all of them yet. Wait for the blue truck to come in (you can see it through the windows in the background). Once the truck is there, aim at the windows and kill the thugs that come out of the truck. All other enemies are fairly easy to kill. Just aim quickly. 2 Shots per enemy should be enough.
Moreover, the trophy / achievement description is a little misleading. You may reload checkpoints, but only the first one after the twins have been killed. Do not reload the checkpoint where you get two pistols.

Romantic
Real guys know how to dance
This is story-related and can only be done in Chapter 4 – Q and A.
The trophy / achievement is fairly simple, but easy to miss. Just don’t kiss Jenny during the dance. After 2 minutes she will walk away. That’s it!

That’s Why I’m the Boss
Impress Dolfo in two different ways
You can do Dolfo’s challenges in chapter 3, chapter 5 and chapter 12. It doesn’t really matter in which chapter you start. You can also come back later via chapter select. In one challenge Dolfo wants to shoot you 13 bottles in 10 seconds. In the other challenge you have to kill at least 20 out of 24 pigeons.

Decisions, Decisions
Refuse to cooperate with Victor in the Interrogation
This is story-related and can only be done in Chapter 7 – Deal With the Devil.
The task is fairly easy… just don’t press any buttons when you shall pick one of your henchmen to get killed. One of them will get shot automatically after a couple seconds.

The Bird is the Word
Avoid being run over in the parking garage
This is story-related and can only be done in Chapter 8 – Home Invasion.
When you progress in the parking garage a car will try to hit you. Make sure you have some good automatic weapons and shoot the car quickly. You can also activate your gun channeling ability to make your shots more effective.

Carnie Kid
Earn a score of over 1000 in each of the carnival games
This is story-related and can only be done during Chapter 13 – Fun and Games.
Soon after the chapter starts you will reach the carnival area and find the first challenge (can’t be missed). You need to shoot ducks. Concentrate on the ones in the middle and the very fast ones on top. You may miss a couple shots and will still get the 1000 points.
After progressing further in this mission you will automatically reach challenge 2 where you have to shoot black colored cardboard figures. Make sure that you do not hit the sheriff or bartender and destroy some of the furniture for easy extra points (bottles, horseshoes, picture frames, horns).
Reload the last checkpoint if you fail.

Versatile Killer
Kill enemies in 5 different ways within 30 seconds
This might sound harder than it is. When you’re lucky you might get it just by playing through the story.
You don’t need to buy any upgrades to get this done. However, the first chance to get this is in Chapter 2 – Payback, right after destroying the electric panel to open up the first door in the game.
Easy kills that count for the trophy / achievement:
1. Anaconda Kill
2. Headshot (requires a firearm)
3. Impaled (throw pole on enemy)
4. Sliced (throw a car’s door on enemy)
5. Demon Arm Kill

2 guys 1 Pole
Kill 2 enemies with one javelin
A javelin is practically every pole you can throw on an enemy. You can do this pretty much everywhere. However, the first chance to get this is in Chapter 2 – Payback, right after destroying the electric panel to open up the first door in the game. After getting the pistol you will go out to the street and some sort of pole is right in front of the door (it’s glowing purple).
Grab it with your Anaconda Arm. Line two enemies up and throw the pole. You can also aim with your pistol to make it easier.

Skeet Shoot
Throw an enemy into the air and kill him with gunfire before he lands
This can be done practically everywhere. Grab an enemy and throw him above you into the air. Simply shoot him while he is flying. Your first chance to get this is in Chapter 2, right after getting your first weapon.

Karma’s a Bitch
Kill a shielded enemy with his own shield
Your first chance to get this is in Chapter 8 – Home Invasion. There will be a shielded enemy on the balcony. Shoot the shield a couple times and grab it. Weaken the enemy some more (weak automatic weapons are recommended) and throw the shield on him. You can also reload the latest checkpoint and try again.
