In Dead Man Walking you will get an Objective called "Locate the Nanosuit Deep Scan Cradle; Locate Gould." Take the elevator down at the end of the level and go down the hallway. Take a right and look for a security camera and a bank of equipment. Hop the red rope and look for a switch. Hold ACTION to activate the switch and a red light will shine. Head back to the elevator and hop another red rope to reach a second elevator. The switch will be glowing. Hit ACTION again to open it and you will see a strange sight: A CELL disco party in the elevator!

If you're invisible when you fire your weapon in multiplayer, you will drain your energy gauge entirely. Be sure to turn off invisibility right before you fire your weapon to avoid depleting your energy.

Choose "Extras" from the main menu and then "Credits." While the credits play, press the fire button five times.

In the New York library, there is a section where you'll have to walk through some fire. Right after this, open your visor and look around for some books pointed out to you by the visor. Scan the books and the Achievement is yours.

Complete the campaign for New Game Plus (you get to keep your armor modules at the least).

While aiming down sights, you can press in the left joystick (Left-Click on Xbox 360, L3 on Playstation 3) to trade energy to steady your aim while sighting "down scope." Use this with Maximum Armor (while crouched) and your aim will be nearly 100% accurate.
