Venice Beach in Dead Island 2 is quite the departure from the game's previous locations with its sun-soaked beaches and brightly colored shops. Just like in other areas, however, you will still find numerous locked safes, lockers, and doors.
The Burger 66 Stack Locker is one such locker you may stumble upon right after entering Venice Beach. That's because it's right next to the Blue Crab Grill safehouse. However, its key is nowhere near to be found, so you won't be able to unlock it immediately. Hence, here's our guide, which explains how to get the Burger 66 Stack Locker key in Dead Island 2.
How to Get the Burger 66 Stack Locker Key in Dead Island 2
The Burger 66 Stack Locker key is on a poison-spewing Slobber called Burger the Server. You can find them lurking around the fountain next to the police station. While the key's location is a bit far from Burger 66, you get to visit this area on two different occasions, one of which is a Lost & Found quest. You can still find the exact location of the Burger 66 Stack Locker key in the screenshot below.
If you haven't faced a Caustic Slobber before, it's best to keep some distance because Burger the Server will immediately cover the ground around themselves in Caustic-X. It's best to kill them using a ranged weapon.
Once you have killed the Slobber, grab the locker key and head back to Burger 66. You can find the exact location of Burger 66 in the screenshot above. Unlock the stack locker to get a Superior-tier weapon.
