Weapons in Dead Island: Riptide are very varied, but one of the most important things about a weapon is its quality. There are five tiers of quality, and from most common to rarest are; White (Common), Green (Uncommon), Blue (Rare), Purple (Unique) and Orange (Legendary).
It’s important to note that a high quality weapon is usually only better than its counterparts in the same type on the same level. So for example, if you find an orange gun, it might get out scaled in only a few levels by a white weapon of the same type. Nevertheless, they’re valuable to find and hoard, so here’s an exploit-ish method that a Youtube user named Deathmule has revealed.
This process allows your entire party to get an unlimited number of Orange weapons through a process that’s only 10 minutes long.
First of all, you need to go Mataka Village and sit inside the shack near the fast travel location for 10 minutes (5 hours game-time). After your vigil, use the travel station to go to Henderson Ferry Station.
As soon as you arrive, turn around and use the fast travel to go to Halai Village. Once you’re finally there, look at the metal shelves to your right. On the second row of shelves, there will be a crate that you can open. At the end of this process this crate will contain a random Orange Weapon. Repeat this process as many times as you like to outfit your entire group with the best weaponry available.
