GRE Anomaly C-A-05 Fight Guide - Dying Light 2

You will need to bring some molotovs, 3-4 should be enough. You will get the blueprint after the unruly brother quest.

Move only on top of the platforms and utilize the spears (there are four of them, one on each platform).

As you move between the platforms,you have to throw either molotov cocktails or gas tanks at the boss.

With fire, you have a chance to set the boss a blaze thus dealing additional damage.

The best time to throw is when he moves (jumps) to a different position and tries to attack you.

You have to repeat until you take him down.
