The achievement will pop up as the credits roll. Story related, obviously cannot be missed. A few tips to help make the level easier:
- There are a lot of red gas/fuel tanks littered across some areas. Use these to your advantage, they can really help clear out a room quickly.
- In the woods, there is an area where floating words are scattered almost everywhere ahead of you. Be very careful which words, if any, you choose to highlight. You can highlight one enemy at a time to make it easier for yourself.
-Be particularly careful when using the ‘boom!’ effects. They may be incredibly helpful in killing enemies quickly, but the explosion can also trigger nearby words as well, meaning more enemies can pop up and may be difficult to see in the aftermath of the explosion.
-Use the blast furnaces to your advantage. Don’t set them all off for the 'Words Will Never Harm You' achievement until you are absolutely certain you have fought every possible Taken in the area, as they can one-hit-kill most, if not all of the Taken you will face there.
-Conserve some flare gun ammo for the final fight. I found a total of eight flare gun ammo and saved three for the final fight, but you may have found more, or perhaps less, so be cautious as to how you use the flare gun.
