Forget weapon and armour upgrades. The first thing you should unlock in Doom Eternal is Doomguy’s retro armour.
There are two little-known facts about Doomguy’s armour in the original Doom from 1993.
First, the classic “besieged by demons” pose was modelled after Id Software founder and legendary Doom designer, John Romero.
“I kept telling the model what to do but he couldn’t see the scene in his mind,” recalls Romero in a blog post. “Frustrated, I threw my shirt off and told him to give me the gun and get on the floor – grab my arm as one of the demons! Defeated, he deferred. I aimed the gun in a slightly different direction and told [cover art illustrator] Don [Punchatz], ‘This is what I’m talking about!'”
And second, the exposed midriff belly-shirt thing he’s got going on? That’s not deliberately sexy armour. (Let’s be honest, it would’ve been weird if it was.) If you look closely, you can see that the stomach panel of the bottle green marine armour has been ripped and clawed away by demons.
That second detail’s important because one of the better features of Doom Eternal’s infernal, eternal upgrades is the ability to unlock Doomguy’s classic armour from the first game. Because you see the big guy animated in cutscenes for the first time it’s a bit weird to see his exposed abs rendered in such detail, but the retro armour is so much cooler and more metal than his modern, shiny demonic Stig armour.
So hot. But how do you unlock it, exactly?
How to unlock the retro armour in Doom Eternal
You can’t unlock the retro armour in Doom Eternal right away, sadly, but you can get it within the first few hours if you prioritise your unlocks. (You could argue that prioritising cosmetics over upgrades is daft, but we’d argue that the retro armour is one of the best things about Doom Eternal. Read into that what you will, or just read the review.)
A few missions in, you’ll run into objects called Sentinel Batteries. You’ll need these in the main campaign to activate Sentinels – those big, ruined robots that litter the world – to allow you to advance through the level. Well, not the whole Sentinel; just an arm or a weapon here and there.
When you’re finished shuffling robots around, you’ll find you’ve got a Sentinel Battery left over. When you return back to the Fortress of Doom – the totally unnecessary hub base in Doom Eternal – you can use that Sentinel Battery to power up the rest of the ship and unveil the rest of its labyrinthine layout.
Once you’ve done that, any additional Sentinel Batteries you find in the game’s campaign can be used to unlock rooms in the Fortress of Doom. You’ll need two Sentinel Batteries per room unlock, so we thoroughly recommend using your first two spares to unlock the retro marine amour. (Pfft! Who needs weapon and armour upgrades when you have such a sexy stomach?)
You can find it at the following location:
And when you shove two Sentinel Batteries into the ports to the left and right of the doorway, this is what you’ll see:
Look at it! It’s flipping glorious!
Time to start working on those abs, Doomguy.

We have a favour to ask
Thumbsticks has a couple of main aims. We want to write interesting articles and cover games that most outlets won't, and we want to give opportunities to new writers and new voices. And right now, with the current state of online publishing? It's tough! We hate to ask, but if you want us to continue writing what others won't, or to keep covering weird indie games, or to be able to give opportunities to new writers – and only if you can afford it – then please consider supporting us on Patreon.
