Dying Light KOREK MACHETE Location Guide
The Korek Machete is a real beast and does almost 500 damage with the benefit of handling incredibly well.
I found two ways to climb up this building but the one i show in the video is a lot less frustrating. You start out in the gated middle area of the building and jump up the center vent. From there you want to look back and grab onto the lamp. Use the balconies to get to the top and look for a box hidden behind some boxes. The box has to be kicked for a while until it opens. It should take you about a minute.
The Korek is a lot of fun to use and just slices through multiple zombies. You can even take out Volatiles at night with a few blows if you surprise it.
