Step 2: Complete the DOOM 3 campaign on Nightmare, collect all PDAs, Video Logs and open all Storage Lockers This step is just if you want to enjoy the game and not worry too much about the trophies just yet.

Even when you play on Nightmare, you might even beat that time. I was able to beat the game and record trophy videos for the PDA locations etc and my final time was 9hrs 20mins. If you're confident enough you can get all the collectibles in this step. Step 1: Complete the DOOM 3 campaign on Recruit, aim to complete it in 10hrs for the Speed Run trophy.

When you're in the Reactor Room you have to climb up a ladder, in rare cases this ladder will not let you reach the higher area (like there is an invisible wall above the ladder). If you don't have this conversation with him then the elevators will not open and you must do this before turning on the reactor, because if you go back and talk to him afterwards it still won't work.

Here is a list of them and how to best to try and prevent them:ĭelta Labs - Delta Lift becomes broken and you can't advance There are a few game breaking glitches in this game you should be aware of so you know when to save your game.
