Korek Machete Location - Dying Light Easter Egg
The Korek Machete is one of the first Developer Blueprint Easter Eggs that you'll have access to in Dying Light. You can get this item extremely early on in the game, any time after visiting Dr. Zere's trailer. You can find the Blueprint for the Korek Machete in the northern portion of the Slums ontop of the same building that houses the Underground Parking Quarantine Zone.
If you're having trouble locating this area use my screenshot below for some additional guidance. Once you've made it to this building, getting ontop of it will be another task. You need to jump onto a lamp from the ground level (use my video for guidance).
