Doom Eternal - Sentinel Prime collectable locations
Where to find all hidden collectables on Sentinel Prime.
Sentinel Prime is the eighth level of Doom Eternal, following on from Mars Core.
A sacred place found through the core of Mars. It's one of the shortest levels in Doom Eternal, with a build up focused on lore, and a really intense fight waiting for you in the massive colosseum pictured in the background.

Doom Eternal Sentinel Prime Codex Entries locations (9 total)
The 'Sentinel Prime' codex entry can be found on the right side of the first platform you land your feet on.
'History of the Sentinels - Part IV' can be found after falling from the first platform, following the main pathway.
Right after the first platform to where you fall onto, keep making your way forward and take a detour right on the centre of the map to find the 'History of the Sentinels - Part V' codex entry.
At one point you'll find yourself looking at an area on the minimap with two codex entries and one Extra Life. In order to get all three, you're gonna want to jump onto a platform in the middle of a room, and then jump again all the way across to a gap on the wall. From there, activate the skull mechanism and then move towards the other extreme of the room, which you just opened. Now, pick up the 'History of the Sentinels - Part VII' codex entry.
After activating the mechanism in the corridor where the Part VII codex entry is located, head towards the end of the passage and, pick up the 'History of the Sentinels - Part VI' codex entry.
Before following the main path, take an underground detour to pick up the 'History of the Sentinels - Part VIII' codex entry.
As soon as the game leads you outdoors once again, you'll be able to pick up the 'History of the Sentinels - Part IX' codex entry.
Before falling inside the hole to the last area, jump across to pick up the 'Deag Grav' codex entry.
As you approach the last area of the level, make sure to grab the 'Gladiator' codex entry.

From there, activate the skull mechanism and then move towards the other extreme of the room, which you just opened. After circling all the way around, you'll be able to pick up the Extra Life.
