Here are our Cheats for Dying Light on Xbox One. The most trustworthy items get the most 'thumbs up' from our users and appear nearer the top!
If you look at the map, go down to the bottom left next to the water and face the broken bridge to the city.
Look to the left and you'll see a rock in the middle of the water. Swim to the rock, climb up and there should be a sword named EXPcalibur stuck into a zombie and pinning it to the rock.
You have to hold down the pick up button for around 60 seconds to pick it up.
Don't immediately jump back in to the big blue though because the body the sword was stuck into will set on fire and underneath will be the blueprints to fix and create a new sword.
If you have more than 99X of an item you can dupe it. First put 15X of that item into your inventory. Then go to your stash and select 99X of that item. Select the option to move all in one go. This will result in 99X of that item and 84X instead of 15X in your inventory.
