Then, you need to kill zombies near the mechanism.

Once you've found all three gears, go through the Passage to the Gearworks and interact with the mechanism to activate it. Directly behind this, underneath the burning plane, is a battery: When you spawn in at the Crash Site, look across from the burning plane that's in front of quick revive and in the rubble will be a wire for you to pick up. I will also assume you are somewhat familiar with the map (knowing the name and location of all the areas and perk locations) so read carefully and let's begin! STEP 1: ENTERING THULE However, make sure you read every step carefully since it is essentially a combination of all 4 upgrades at once. So, I believe the order I have this Easter egg structured is the most efficient and quickest way to complete it. The reason being is that you'll want to complete all of these steps while on the lowest round possible.

Obviously, the process of completing it is more complex than that, but I mention this because although you can do the upgrades for the melee weapons in any order (like on previous maps) I do NOT recommend you focus on one upgrade at a time. IMPORTANT: The Easter Egg for this map is essentially this: Get the 4 melee upgrades -> Enter Boss fight -> Defeat boss I'd personally recommend the 9mm SAP over the M1911, because I think the Pack-a-punched version of it is more useful than the upgraded 1911's, but if you're in co-op you can split it between your partners so some have the SAP upgrade (very powerful) while others have the bacon and eggs (good for clearing groups of zombies and defending teammates). For starting weapons, everyone should have either the 9mm SAP or the M1911 pistol.
