Wanted: Weapons of Fate

This Achievement is awarded upon completion of the first chapter of the story when played on The Killer (hardest) difficulty. Act 1 is pretty much straight-forward shooter fare. Use the many objects for cover and use the A button to dart from one hiding place to another. Save your ammo and wait for enemies to poke their heads out before firing - and go for the headshots. You won't have to worry about curving bullets here, as you unlock that skill upon completion of this Act.

There's a quick-time event toward the end of the level. When things slow down, just take down the enemy before your time runs out. In some cases you can get away with not killing the enemy and still make it through alive. Just make sure when you dive through the window to the building across the alley, you shoot the bullet as well as the enemy target. Missing the bullet will almost surely kill you.

When you reach the SWAT captain, use your blind fire to force him to take cover behind his shield. The screen will tint white at the edges to indicate that he's not looking in your direction. Use this opportunity to dart to the cover on the opposite side from where you are currently. You'll be able to pop off a few shots to his undefended side before he reorients his shield and blocks you again. Rinse and repeat and necessary until he retreats. You'll use this same strategy when you face him for a final time a little later - but you'll want to be quicker because his shots will start to wear down your cover and a couple other cops will show up to further distract you.

You will have to complete all nine acts of the game on Assassin difficulty first before you can unlock The Killer difficulty.
