If you're looking for all the collectibles from Phase One of Doom Eternal, see the Hell World guide.
Here you are looking for three toys, six codes, three modbots and one cheat code. Here's how to track them all.
First you need to struggle in the small living room and then walk through the door. Go left and then down the stairs.
Keep it straight and keep the wall to your left until you reach the end of the room. Now, go through the cracked wall.
Go down the secret tunnel and finally jump up, Zombie (Earth) Toy.
Go straight ahead and follow the room until you see a cube with a green symbol. Punch the cube. carry on.
Now, once you move to a higher floor, climb to the top of it. Get the mod from modbot.
Go straight to the battlefield. Clear it and move on. You will find a Codex in the next corridor.
At the end of the area, you will trigger a cutscene and then go to the second map of that level.
Next, you will be in a ruined city on the streets of the earth. Right in front of the departure point, there is a manuscript, The Remaining Population, Part 1. When you climb to the next area, you have a modbot.
Punch the crack in the wall forward, and immediately jump up to the left when you are on the other side. Find along this road Doomsday Toy.
Now pull down and fight through demons. Once they die, they climb up on the other side and swing across the monkey bar.
You will fight here to kill all the bad guys. When done, leave the arena and collect heavy cannons. Climb and collect maps of the area.
Enter through the door and enter the room with a big bell. The battle passed. If needed, there is some armor on the floor above the bell.
Walk into the streets to clean up the demons. Once they died, there was a building with the "ShuZ" logo on the left side of the Scott building. Enter the ledge above the sign and enter the interior. There is a wall with cracks on the left. Please punch holes.
Put it in the room below Little devil toy.
Struggle down the street and climb into the ruined building to the left of the door that requires a yellow key card. Reaching the top floor of this building, you can skip a blank and collect the remaining population of Codex Part 2.
Land outside the room and enjoy extra life.
Now back to the building opposite the street and the key card door. The thorns crack the seams and kill the demons inside. There is also a crack near you that can increase life.
When you are done there, head to the ramp and jump to the climbable wall. Collect the keyboard and place it underground.
Fight in the hallway, being careful not to get hit too much from the trap as you walk. At the bottom of the stairs, on the train platform, there is another modbot.
Cross the train, cross over and deal with demons in the next arena.
Continue following the level until you reach the end of the three climbable walls. You will find another codec at the end of the track.
Now, use the tentacles to fight through the room until it splits. One method is to take you up the stairs, and the other is to use a box. Jump onto the box and climb into the vent. You can find the cheat code here.
It's the collection in the first stage of Destruction of Eternity.
