Find the Super Turbo Turkey Puncher 3 Mini-Game in Doom
First up, make your way to level 8, which is the Advanced Research Complex. You'll want to make your way into the corridor, as noted in the video below. You'll come across a section where you need to activate an airlock first. Wait a few seconds after you do this, and the doors will open up.
Now, don't run off, as the game will be located right here in this room. Instead, make your way over to the crates that are right in front of you. Go ahead and start jumping over them, and you'll see a little area where the Super Turbo Turkey Puncher 3 game can be found. Stand in front of it and click in the right analog stick to get it started.

Gameplay is relatively easy. You've got a turkey in front of you, so just hit it as many times as you can. Eventually, it'll vanish into a bloody heap, but then another turkey will appear, and you can repeat the process over and over again as you begin to build up a high score.
Does it have much of a point? No, but it's a neat little Easter Egg that's fun to kill time with for a few minutes, before you get back to killing demons for real. Take that, turkeys!
