How to complete Doom The Dark Ages 'Barrier Core' mission

In this mission, your primary goals are to:

• Defend the barrier, and the city of Hebeth
• Secure the overloaded power core
• Get rid of the overloaded power core

As stated above, you kickstart the mission by commandeering the Atlan. This bipedal machine has enough juice to knock out Titans in a few swift combos.

Without further ado, let's start with our mission.

1) Exit the Hangar - Learn to comandeer the Atlan

Start the mission by getting off the Hangar. As you step into the chaos of the battlefield, you will find yourself wearing some brand-new gear. This is the Atlan.

Commandeering the Atlan, you get access to two melee attacks, a sprint, and a dodge. The primary attack can be used to land combos, and as you fill the finisher-meter, you can use your secondary attack to deal finishers against Titans.

2) Defend the Barrier

Now, once you get the hang of how you can use the Atlan, you must fight against the massive Titans on their way to wreak havoc against the city of Hebeth and its protective barrier.

The gameplay sequence here is pretty linear. Keep following the markers on your map, and as you fight against the Titans. Doom the Dark Ages will provide you with tutorial prompts on how you can use the various parts of the Atlan's kits to fight against enemy Titans.

3) Clearing out Titans

The easiest way to defeat these foes is to use the primary attack combos against them. Be cautious, as they will definitely hit back. When they do, use your dodge to successfully parry the enemy's strikes.

A successfully executed parry opens up a major window of opportunity for you to strike in Doom The Dark Ages. Lay down a flurry of punches, and use your secondary fire to execute a palm strike finisher when the combo-meter eventually fills up.

4) Unlocking a minigun for the Atlan

As you make your way through the Titans, you will come to a point where you're met with a cutscene of King Novik blasting the head off of one of these foes. Right after, you will unlock a brand-new weapon, a minigun, for the Atlan.

The minigun is perfect for shredding through Titans, however, it's even more powerful when you can supercharge it. To do so, execute perfect dodges against the enemy. It will supercharge the weapon, and taking down Titans becomes as easy as slicing through butter.

5) Head to the power core

Fight your way through the demons and make your way to the power core. Once you reach it, you will trigger a cutscene. The Slayer will reach for the core and take it in his possession.
