Amnesia: The Bunker

The lighter is worth it cause it allows you to use petrol bombs, serves as a smaller light source, and in general is just a useful tool to have. Unfortunately, the dog tag is a little bit difficult to track down.

You need to look for A Giraud's dog tag, which can be randomized to over 10 different locations in the game. Some have said it tends to be in maintenance, but I found it once in Mission Storage and by the Generator... so it could be anywhere.

I covered all the locations in this achievement video... and it'll show you how to get the other achievements associated with fire related fun in the bunker. 0:24 is where the explanation starts!

The Lighter is located within A Giraud’s locker in Munitions Storage, which will require the code found on A Giraud’s dog tag.
