Information is Power
Collect all evidence
There are a total of 45 evidence collectibles in Hitman: Absolution. Finding all of them will earn you the Information is Power trophy / achievement. They also give you other small awards such as bonus points and instinct. On high difficulties the bonus instinct will come in handy! The evidence is also required to complete the challenges of each level. The “Evidence Collector” challenge keeps track of your progress. You can check it out by clicking on “Unlocks” in the Single Player Menu. After collecting the evidence it will be saved automatically and you can quit the level immediately.
The instinct ability will highlight nearby evidence and makes it easier to find everything. Click here for a full Text Guide.

IMPORTANT: Your challenge progress will not be saved on easy difficulty! The trophy / achievement won’t unlock either. You have to play on normal or professional.

Damage Control
You contained a situation gone bad
Location: Level 2 – The King of Chinatown
To do this you have to become suspicious by causing property damage, killing people or running around with your weapon. You will then have to escape your enemies by killing all of them or hiding in a dumpster. Wait until everything turns back to normal.
After going through the gate in the beginning of level 2 go straight and make a left. You should see a single police guard next to a car and some explosive barrels. Shoot the barrels to cause some carnage and hide in the nearby dumpster until the investigating police officers are gone.

It’s All in the Wrist
You successfully performed a lethal throw
Location: Level 2 – The King of Chinatown
Search for a lethal weapon in any of the levels after the prologue and pick it up. The most common lethal weapons in the game are knives. Go into aim mode and search for a nearby person to kill. Aim on the head and throw the knife. The enemy has to die!
After going through the gate in the very beginning of level 2 you can find a knife near some dumpsters on the left. You can also kill one of the merchants with it.

One of the Guys
You blended in and fooled someone
Location: Level 2 – The King of Chinatown
After going through the gate in the very beginning of level 2 you will come to a market place. Some of the food stands have magazines on their counter. Press Triangle (PS3) / Y (X360) to interact with such a magazine while an enemy or police guard is nearby.

One With the Shadows
You escaped the attention of an enemy
Location: Level 2 – The King of Chinatown
After entering the marketplace in the beginning of level 2 go to the right until you reach an alleyway with a guard. Kill the guard as well as some civilians and wait for more enemies to arrive. Once you’ve got their attention, go up the stairs into the room where “Snowman” (guy with in white clothes & sunglasses) is hiding. Take him out and use his clothes as a disguise. Hide in this room and wait for a couple of seconds until everything turns back to normal.

Rocksteady
You executed a point shooting with at least 3 kills
Location: Level 2 – The King of Chinatown
You will get to know the point shooting ability during a tutorial in the prologue (level 1). To use it you need to activate your instincts and press Square (PS3) / X (X360). Then you can mark several targets to be eliminated. This even works against civilians. Right after leaving the starting area of the second level you will run into lots of civilians on a marketplace. Shoot three of them with this ability.

Sandman + Under Wraps
You subdued a person
Hide a body
Location: Level 2 – The King of Chinatown
To subdue a person you need to equip your bare fists. Attack them from behind to choke and render them unconscious. After that drag the person to a nearby dumpster and hit triangle (PS3) / Y (X360) to throw them in there. After going through the gate in the very beginning of level 2 there will be a dumpster to the left. Normal civilians cannot be subdued. Search for a merchant or guard. Persons that can be attacked are marked in yellow when activating the instincts.

Whoops
You made a kill look like an accident
Location: Level 2 – The King of Chinatown
After going through the gate in the very beginning of the second mission, go straight until you reach the end of the marketplace area. Pick up a brick or any other object (e.g. bottle) that can be thrown to make some noise. There are two guards standing at the end of an alleyway to the far left and some wooden pallets hanging in the air close to where the guards are standing. Go behind the guards once they start their patrol (so that they cannot see you) and throw an object underneath the wooden pallets. One of the guards should come to investigate. Shoot the metal thing that is holding the pallets when the guard is standing underneath.

The Russian Hare
You performed 47 headshots using a sniper rifle
The 47 sniper headshots can easily be farmed in the very beginning of the last level called “Absolution”. You will start this level with a sniper rifle and 10 bullets. There are more than 10 enemies in this area. Kill as many as you can with headshots and restart the checkpoint when you run out of ammo. After restarting the checkpoint your overall headshot kills will be saved and you get back your ammo. Repeat this until the trophy / achievement pops.
