Mars Core Doom Eternal Mission 7 Toys Locations

The first toy location in Doom Eternal Mission 7: Mars Core is right after you take the long elevator ride. On your left, you’ll see the control panel the mission leads you to. Go down the corridor on the right instead. There, you’ll find a question mark with the Toy Prowler.

As you progress through the level, you’ll have to progress through a bunch of huge gate-like structures on the map by boosting through towards the blue jump pad. Proceed to the room that looks like it has a large pedestal in the middle on the map. Behind that pedestal-like structure is the question mark with the Toy Carcass.

During the Get to the Escape Pod section, you’ll find a locked door, behind which you can see some zombies and the question mark. Drop down to the level where the escape pods are. As soon as you drop down, look left and punch through the vent. Go into the next room and use the blue jump boost to reach the locked room with the question mark. The Toy Pinky is in there.

When you go through the gate-like structures described in the second toy entry above, and use the blue jump pad, turn around. Use the yellow bar and boost your way into the vent with the question mark. The DOOM 64 Intro track is in there.

For the second album, with your back to the Slayer Gate, head straight forward until you come across the Operations window. Jump onto the square platform on the right, and look above and to the left. You’ll see a vent grate that you can punch through, so do just that. You’ll see the question mark, in which is the Quake Champions: Goroth track.

Where to find Mars Core Cheat Code in Doom Eternal?

To find the Mars Core cheat code in Doom Eternal, head to the left from the room with the pillar in the middle and two huge System Critical screens. Proceed through the melted hole in the wall on the right, then through another melted hole, again to the right. You’ll see the question mark in the corner; be careful not to drop into the hole. The question mark has the Powerup Mode: Onslaught cheat code.
