2. Destroying Dahl Defense Cannons - Tips

Use the Rocks To Break Line of Fire

The Dahl defense cannons can instantly lock on and deal devastating damage to you. However, you can avoid their fire by hiding behind the rocks around the area. You can also peek above it to fire back at the cannons!

5~6. Repairing the Turret - Tips

Electrified Skrich Heart & Fuse Location

The map above will show you the locations of the electrified Skrich heart and the fuse.

Kill Skriches Until One Drops the Heart

The electrified Skrich heart will randomly drop from one of the electrified Skriches that you kill. Just keep on fighting the Skriches until the item drops on the ground.

Use the Ledges to Bypass Electricity

The fuse will be behind a pool of electrified water. You can avoid taking damage from this by climbing up onto the boxes, and jumping from ledge to ledge until you can drop down to the other side.

8. Killing Bonded Enemies - Tips

Destroy the Dahl Defense Cannon

If you look up, there will be a Dahl defense cannon on the ceiling. If left alone, it can shoot you down while you are focused on other targets. It is best to prioritize taking this down first to avoid getting blindsided by a potentially fatal attack!

Utilize the Thrusters to Burn Enemies

Most of the enemies that you face in this section of the mission will be vulnerable to fire damage. If you can lead them to the right spot, the thruster will be able to burn them for some damage!

13. Get the Mainframe Door Open - Tips

Connect the Wires Using Water

The wire needed to power the mainframe door does not have electricity. There will be a pipe which you can destroy to create a puddle. This puddle will be electrified, which will send some power to the mainframe door.

19. Stabilizing the Reactor - Tips

This is a Scripted Event

No matter how fast you try to stabilize the reactor, the end result will always be the same. The reactor will overload Deathtrap.

Empowered Grawn - Boss Battle Tips

Will Be Immune to Start the Battle

The Empowered Grawn will start the battle in an immune state. There is nothing you can do about this state except buy some time. It would be best to focus on taking down the minions that it spawns to lessen the number of threats in the area instead.

Deathtrap Will Help You Out

After some time, a cutscene will trigger, and Deathtrap will blast the Empowered Grawn. This will make the boss vulnerable to your damage! If you were able to take out the other enemies, you will be able to focus your fire on the Grawn!

Use Incendiary Weapons

The Empowered Grawn will not have any shields or armor. You can easily whittle down the boss' health by using an incendiary weapon on him!

Will Sometimes Become Immune

At times, the Empowered Grawn will enter an immune state. During this state, there is nothing you can do but wait. Deathtrap will eventually fire a laser at the boss and make it vulnerable again.
