How to Beat the Two-Head Boss

Tips for Beating the Two-Head Boss




Aim for the Head!

The Callisto Protocol - Aim For the Head
The Two-Head Boss is weak against attacks on the head, unlike any other enemies in the game. You should always aim for its head to increase the chances of staggering it on the field. It will give you some space from it using that trick or you can slip in an attack before it recovers.

Destroy One Head with Melee Once it Kneels

The Callisto Protocol - Remove Head
It is also possible to destroy one of its head as you fight it in the game. You will need to deal enough damage to make it kneel on the ground and be open for a consecutive hit from your melee, smashing one of its heads into pieces in the process.

Use melee attacks again the second time it falls on to its knees to finish it off completely.

Keep Some Distance by Sprinting

The Callisto Protocol - Sprint
Since Sprinting is unlimited, you can always use it to run faster and avoid getting too close to the Two-Head Boss. It wouldn't be enough just to run as the boss can still catch you, but you can avoid it if you use the obstacles as cover or shoot it as you run.

Dodge Attacks When the Boss is Close

You can also dodge the attack when he gets too close and pull out a counter attack. Run and sprint away until it's safe to shoot and attack again after that.

Use the Riot Gun or Skunk Gun

Although using melee attacks do better damage, Riot Gun and Skunk Gun are still better as they will let you deal massive damage against the Two-Head Boss at a safe distance. If you land a good hit, it can also stagger the boss, which will give you some time to gain distance.

Learn to Quick Swap Weapons and Health Injectors

Knowing the quick swap buttons in the game would help you greatly on your fights against the Two-Head Boss. It will take up a lot of time just to open the Inventory and use the items that you need, and the Quick Swap function will help you deal with that.

Always Prepare Before the Battle

The Callisto Protocol - Ammo on Reforge Terminal
You will encounter the two-head boss multiple times in the game, but you will always have time to prepare for it. Use that time to upgrade weapons, remove unnecessary items, and stock up on supplies before heading to battle to increase your chances for survival.

First Encounter Guide

Two-Head Boss First Encounter Guide
(Chapter 6: Below)
1 Survive Incoming Enemy Waves
You will face tons of enemies first before you start your battle with the Two-Head Boss. You can use your Skunk Gun and GRP to take them out quickly. Stay near the edge to make it easier to throw enemies outside the platform with the GRP.
2 Loot Chests as You Battle Enemies
There will be chests scattered around the area as you fight enemies on the platform. Loot them when you get the chance to recover ammo and batteries to keep you going.
3 Fight the Two-Head Boss
After surviving the enemy waves, the Two-Head Boss will finally make its appearance. Use your Riot Gun and Skunk Gun to deal damage while keeping a safe distance. You can also use the surrounding crates as cover to avoid getting caught by the boss.
4 Remove One of its Head
Once you've accumulated enough damage, the Two-Head Boss will finally fall on its knees. Use that chance to perform consecutive melee attacks and remove one of its heads.
5 Finish the Two-Head Boss
Removing one if the heads won't be enough to kill it. Use the same strategy earlier with the Riot Gun and Skunk Gun until you beat the boss.

Second Encounter Guide

Two-Head Boss Second Encounter Guide
(Chapter 7: Colony)
1 Fight the Two Head Boss
The Two-Head Boss will spawn as soon as you enter the boss's area. Shoot it while keeping a good distance to avoid getting hit by its attacks. You can use the covers around the area to outmaneuver the boss.
2 Take Out Weaker Enemies Quickly
There are two weaker enemies that'll spawn and join the battle. Take them out quickly with a shot from the Riot Gun or use the GRP and spike them to the wall.
3 Look For Loot Around the Area
You might find yourself short on resources as the fight goes on against the boss. There will be supplies around so try to look and see if you can grab some.
4 Use the Explosive Tank to Immobilize the Boss and Remove One of its Heads
You can find an Explosive Tank inside a room near spikes on the wall in the area. Use the GRP to grab it and throw it to the Two-Head boss to immobilize it. You can then perform a melee attack that will remove one of its head.
5 Continue Attacking and Finish the Boss
Continue attacking the boss with your guns and still keep your distance until it goes down again. Finish the boss with a good melee attack and move on to the next part of the story.

(Chapter 8: Tower)
1 Enter the Room and Fight the Two-Head Boss
You will be able to see the Two-Head Boss standing around the corner as you enter its area. Start attacking it with your guns before he closes in for an attack.
2 Keep Shooting Until it's Down
Keep on attacking until the boss is down on its knees, then take out one of its heads. Consider dodging if the boss gets too close and can reach you with its arms.
3 Switch Guns and Heal Up When Needed
You will surely empty all your ammo on your current weapon mid-fight. Go around the obstacles in the area, dodge attacks if necessary, and use the Quick Swap button to switch guns quickly. You should also heal up if you're close to dying!
4 Continue Attacking and End the Boss
Once you've changed guns and are back to full health, resume attacking the boss until it falls again to its knees. Perform consecutive melee attacks once it happens to finish the battle and kill it.

3 Repeat Step 2 and Finish the Boss
After smashing one of its heads, immediately run and look for another Explosive Tank. Throw it again on the boss to make it fall on its knee. Then end the boss with a good smack on the face using your melee weapon.
