Hey Gamers! Welcome to DOOM Eternal!! I show ALL collectible locations, encounters, go over the challenges, and slayer keys/gates.

Before you start be sure you select Extra Life mode so we can get the achievement for finishing that with more than 10 lives (Guide shows all Extra Life locations as well!).

Of note, nothing is missable you can replay missions to get anything you missed (unless you are playing Extra Life Mode - SEE BELOW), and also you will be given the option at the end of levels to warp to specific sections to grab anything you missed which can alleviate having to play the entire mission again. Every collectible and item will be time stamped in the video comments and description!

**Please note if you are following my guide to get all campaign related achievements in one playthrough and are playing Extra Life Mode, MISSION SELECT IS NOT AVAILABLE IN THIS MODE so be sure you collect all the collectibles in the first playthrough and use the fast travel option to grab anything you may have missed BEFORE EXITING THE LEVEL!***

**This particular achievement is tied to collecting all of the Cheat Codes in the game. The cheat codes are timestamped in the comment and description section of the video! ALSO, one of the cheat codes is obtained by FULLY UPGRADING YOUR PRAETOR SUIT to get the Quakecon Mode Cheat Code, which I unlock in Mission 11**

I hope you find it helpful!
