Defibrillator Upgrade - p. 3 | Main missions Rage Guide
Last update: 21 June 2019
A moment later you'll be attacked by the Giant Mutant.
Your opponent has two types of attack, which he uses alternatively. In the first phase he rips off chunks of buildings and tosses them at you. Avoid them by moving to the sides and try to hit him with the rocket at the blue spot on his belly. It is exposed only for a moment when the creature raises his arm to throw so try to shoot a rocket a little earlier (so it can reach him).
After being hit the Mutant will approach you and start pounding with his fists. A hit point is indicated by the red laser so just avoid these points. A moment later the monster will scream showing a blue point on his head. You must hit it with the rocket.
Repeat all these actions several times and you'll kill the giant. Rockets can be replenished at the same place where you found the Rocket Launcher.
When the fight is over, move to the left. Collect ammo from the cabinet and then go down the stairs to the ground floor.
Prepare for the fight with regular mutants. Move forward killing them. Eventually you'll reach an out of order escalator.
At the top of it you'll meet other creatures and one Mutant throwing fire bottles at you. I suggest going back to the lower floor, killing charging enemies and then getting rid of "thrower".
After clearing the area you can go to the upper floor using the stairs on the left.
It will lead you to the hospital. Follow the corridor. At its end you'll get to the room with many useful items and the Defibrillator Upgrade you need.
Pick it up and prepare for the mutants' attack. They will charge at you from the room to the left.
After you kill all enemies go down the stairs and run straight forward until you reach the exit leading to the Wasteland.
You can now return to Kvasir who will install you the upgrade and give you back the Feltrite Sample.
Just take the sample back to the Mayor and the quest will be completed.
