Dead Island Glitches
Duplication
1) When you pick up a melee weapon (Paddle,Knife,Hammer and Axe ect) Press RB and choose one of the melees you have. Then when you have it equipped hold LT then press RT to through the weapon. As soon as the weapon is in the air press up on the depad, go into your inventory and the weapon you through should be still in your inventory. Go to that weapon and press Y to drop it, then when it is dropped press B to get out of your inventory and you should now have to weapons that are the same. Note: You can only duplicate a paddle, knife, hammer and axe ect. You CANNOT duplicate guns and you will not be able to do this glitch if you have done an update of the game.
Invinsibility
2) When you have a big horde of zombies chasing you run into a corner and press RB to kick the approaching zombies. Note: Your stamina will not go down while you kick and this will not work if you have done an update.
Easy Money/Duplication
3) This cheat works much like the duplication glitch does. You need to be at a check point with ready access to a store and you should be in possession of
damaged weapons also. The life guard tower works best for the sake of convenience, but you can perform the cheat near any checkpoint. Start by spending all of your money at the nearest store (on upgrades and repairs), then find a position near the checkpoint and drop everything that you bought,
upgraded, or repaired. Kill yourself, but don't let the countdown timer start. Instead, quickly press the START button and load the game from
the recent checkpoint. You should now have all of the broken and un-upgraded weapons in your inventory. Sell them, then find the place where you dropped
those same items and they should all be waiting for retrieval. You should also have all of your money that you had recently spent.

Throwing Weapons In Fury
4) While playing as Logan, hold LT then hold B while aiming at multiple zombies, then press RT. Instead of Logan using his knives, he will throw the equipped weapon, causing the game to duplicate your equipped item.
Infinite Diamonds/Easy Money
5) When you are in Chapter 7, City Hall Part 2. After you have killed the mayor, open up his safe and there will be one diamond in there. Collect it and then run back into the sewers, then turn around and go back into the mayors offices and open up his safe again and there will be another diamond. The diamond will always reappear as long as you go back into the sewers and then return to his office again. You can sell these for $1500.
Easy Molotov

When you enter the motel follow your map and you will come across a kitchen on your way, on the shelfs are about 10 bottles of alchole. Take the bottles and leave the motel, after you left the motel walk back into the motel, go back to the kitchen and there will be about 10 more bottles of alchole. Take the bottles of alchole and repeat. after you have got as many bottles as you want go to the life guard tower and you will see mike, give him the bottles and he will make you molotoves. Note: Every time you leave and re-enter the motel the alchole will keep spawning. Molotoves normally kill the infected instantly.
