How to Beat the Two-Head Boss

Tips for Beating the Two-Head Boss
Aim for the Head! Keep Some Distance by Sprinting Use the Riot Gun or Skunk Gun Learn to Quick Swap Weapons and Health Injectors Always Prepare Before the Battle

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

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

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

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.

Two-Head Boss Encounter Guide

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.

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!
