You will get this achievement for finding the "Laserkraftwerk".
This is Story-related and cannot be missed.
At a certain point in the game you'll find yourself locked in a lab. To get out of there you have to get the "Laserkraftwerk" out of a big glass-container.
All you have to do is press the button at the side of it, then move on top of the glass-container (or on the side of the button surrounding) and cut those chains with your Laser-cutter. After that press the button again and the "Laserkraftwerk" will cut a big hole in the Container. Get in the Container and take the "Laserkraftwerk" to get your achievement.
