Predictable but scares the crap out of me

First time playing Doom 3. Years of waiting and I finally get to play it. It’s not like the Doom I remember. It’s a complete reimagining with more story.

Um ,I used to be able to bring up the chat console and enter in a cheat code. I can’t do that anymore. Can someone help?
