All The Forsaken Plains Collectibles In Doom: The Dark Ages

The tenth level of Doom: The Dark Ages contains four collectibles for you to seek out in hidden areas around the map. Collectibles consist of optional items, like codex entries, toys, and weapon skins. The total number for each level is shown on the map screen, which also tracks any you find.

There is a fortress on the western side of the main map, where you are destroying turrets. The secret key is here in a locked cell, which can be entered by jumping to a shield jump statue behind the cell and dropping down into it.

The codex entry can be found after entering the large main area and getting the rocket launcher. From the start, head to the right, and you can find a cave with an upgrade shrine in it. Head through there past some traps to find the codex page.

Off to the left side of the main big area, there is an arena blocked by the need for a secret key. Past that there is a small ledge you can drop down to, which has a lift, sending you up to a platform where the toy is.

In the left half of the area, towards the center, there is a secret key-locked door. With the key, head through and follow the path to grab the codex entry.

This can be found near the far right tower you need to destroy. A protective barrier will block this until you destroy the tower in the area. Even if this is your second tower, destroying it will not complete the mission, so don't worry.
