Finally got back to Alan Wake after my first playthrough about 1 year ago. I completed the game on normal and tried to pick up as much collectibles as I could without any guide. I managed to find all tv's and radios and also did every little achievement on the way "play it twice etc.".
I used this guide as I went through the game again on nightmare and found it actually quite easy to collect everything and complete the game at the same time. I had to give it to the maker - this guide was really easy to follow and well detailed. I only had problems at sign 24 and 25 because I didn't read it well.
Thank you !
