How to unlock the It's The Only Way To Be Sure achievement in Aliens Colonial Marines - Definitive Guide

This is done during Mission 4 when you're tasked with opening a door blocked by a machine and also venting gas out of a room.

In the first area there are -
2 Chest Bursters in glass jars as soon as you enter the room.
7 Eggs (2 burned with a switch, 2 above the medical tables upstairs, 3 more eggs in the middle room downstairs - same room as the face huggers.)
3 Face Huggers (inside glass jars in the middle room downstairs)

In the second are there are -
10 Eggs (2 as soon as you enter that you burn with a switch, 8 in the room with the second switch)
4 Chest Bursters (as soon as you enter the room immediately following the second switch room)

So in total - 26 things you have to destroy. If you don't have this by the time you purge the gas and get ready to go through the next airlock, you've missed something. Go back before going through the next airlock door, otherwise you'll be stuck outside and have to reload a checkpoint.

Edit - Thanks to Pic3k for linking me to a video posted by SKSenior over on YouTube.

Other than the fact that the switches destroy 3 eggs, not just 2, this was helpful. +1.

The wording of this achievement can be confusing. This is done during the fourth level. You do not have to destroy any eggs or anything else in the first half of the level. The opportunity to unlock this achievement happens in the rooms full of gas. When you enter the rooms, look for test tubes holding eggs, chest busters, and face huggers. They will be on pillars standing level with your face and easy to spot, or will be hanging from the ceiling above operating tables. There are a few eggs in glass chambers that require you to hit a button to destroy them with fire as well. Just make sure to clear each room out before leaving it.
