How to Upgrade the Tesla Gun in CoD WW2
After getting the Tesla Gun during the casual easter egg playthrough, you can upgrade it to reach it maximum zombie-killing potential by unlocking its four elemental variants found within The Final Reich map. The four variants are Hurricane, Bloodthirst, Reaper, and Midnight, and in order to get them you have to know a few sneaky things about the map to get the items necessary to unlock them. If you’ve been planning on taking a stab at beating the hardcore easter egg in Zombies, which as the name suggests is much harder than the casual easter egg, then upgrading the Tesla Gun is pretty much a necessary first step to make getting that hardcore easter egg ending all the easier.
If you haven’t gotten the Tesla Gun yet, check out a step-by-step guide here. Otherwise, here is a breakdown on how to get all four of the vairants in order to have an easier time at beating the hardcore easter egg mode in CoD WW2 Zombies.
HOW TO GET THE BLOODTHIRST VARIANT
Bloodthirst is one of the tougher variants to get, but allows your Tesla Gun to shoot out bolts of red lightning that stun any nearby zombies and causes them to explode after a few seconds.
The first thing you need to do is go to the street lamp seen below right outside the courtyard of The Final Reich map. Look up at that streetlamp and shoot it a couple times with the Tesla Gun until some green static effects start appearing on the light itself.
Once you see this just shoot the light (the actual light bulb) with a normal weapon such as a pistol, and you’ll notice the next light behind it will start having green sparks in its bulb to. The trick is to go along and shoot every light in a row that has these green static sparks in them, and you’ll know you hit them correctly when you hear an audio cue each time you land a correct shot. There are a total of 25 lights to hit, and they lead you through the map and down into the morgue area. If you mess up the order or get mixed up on which light you are on, just return to the first light post in the courtyard to start again, and make sure all the doors in the path are open down to the morgue to have an easier time hitting every light.
Once you do this, a battery pack will fall from the ceiling onto the floor of the morgue. Putting the battery into the charger in the same room will start charging it. In order for the battery to be charged you need to kill at least one pest zombie (the ones with the flies that arrive on a round that’s a multiple of 5 so 5, 10, 15, 20, etc.) with the spike trap in that room. This can get pretty tricky and might take a few tries to get, but essentially just horde as many pest zombies in the morgue by running in circles and try to time the detonation of the trap when they would be near the battery pack when they are killed. You’ll notice the battery charge turns green when a pest zombie is near it, and if you kill a pest zombie by it successfully some red lightning sparks will shoot into the air. Then just pick up the battery and move on to the next step.
To continue you need to have finished the Lightning Rod defense sections of the casual easter egg playthrough, so if you haven’t done that then go back and complete those before continuing with this guide. If you have completed those then take the battery pack up the stairs of the morgue to the red glowing machine seen below and insert the battery into the hatch on the left hand side.
Some zombies will arrive and start attacking the machine, but just kill them and protect the battery until a Tesla part comes out of the device. Then you just have to take the part up to the Command Room where you first got the Tesla Gun and the option to build the Bloodthirst variant will be available on the four-sided table.
HOW TO GET THE HURRICANE VARIANT
The Hurricane variant is pretty easy one to get, and grants your Tesla Gun the ability to shoot a huge pink ball of electricity that expands as it travels forwards and kills whatever zombies are in its radius.
During the casual easter egg path, an objective will have you open a Salt Mine door. As soon as you open this door there will be several bomb zombies which, as you can probably could have guessed, have bombs strapped to them. Do not shoot them and instead lead them back into the Laboratory area of the map and up some metal stairs so they are right beside a metal locker in the wall seen below.
Kill the bomb zombie near the locker and it will break open and reveal a battery inside. Take the battery back down the stairs and place it in the charger inside an electric trap in the hallway. To get it charged you need to kill several zombies that have these massive clubs on their arms, so bring them into the trap and kill them with the electricity to power the battery. This might take a few tries to do it successfully, so try and bring through as many club zombies as you can find with every try.
Once the battery is charged just take it back to the Laboratory are into the yellow-glowing machine on the right hand side. Once it is placed in the machine you will have to kill any incoming zombies and protect it while it creates the Tesla Gun part. When the part comes out just take it to the Command Room and place it on the table where you first got the Tesla Gun to unlock the Hurricane Variant. To do so, you’ll have to have finished the Lightning Rod quest in the causal easter egg path so the option to upgrade shows up.
HOW TO GET THE MIDNIGHT VARIANT
The Midnight variant for the Tesla Gun shoots a deadly beam of green line in a straight line ahead of the player, and is an amazing tool to use to finish of a horde of zombies chasing you.
To get the Midnight variant you first have to kill a Brenner zombie which are larger enemies that wield flame-throwers and have a big gas-tank on their backs. They spawn normally in The Final Reich map so finding one to kill shouldn’t be much trouble. Once you kill one its head will appear on the ground as an item to pick up, they have several other uses in the game but in regards to the Midnight variant you’ll have to take the head to the Courtyard area of the map and hold it up with L2 (right mouse button on PC) to hold it up to the statue seen below that will emit a purple light.
Once you do this the statue will break and a battery will be revealed. Shoot the battery with your Tesla Gun and it will fall to the ground so you can pick it up and put it in the battery charger directly to the right of you. After it is placed in the charger you need to lead a horde of zombies up to the courtyard and kill them with the lightning trap there to kill them and charge the battery.
Like the other variants, you need to have completed the Lightning Rod quest in the causal easter egg path. Once that is done just pick up and take the battery to the Laboratory and place it in the left hand side of the yellow-glowing machine. This will trigger a defense sequence where you’ll have to kill zombies and defend the battery until it is done inside the machine. The part will show up in the center of the machine and now all you have to do is pick it up and bring it back to the Command Room where you first got the Tesla Gun and place the part on the table to craft the Midnight Variant of the Tesla Gun.
HOW TO GET THE REAPER VARIANT
The Reaper Variant of the Tesla Gun allows players to freeze a targeted zombie, and cause its body to explode after a few seconds that damages any nearby enemies.
Firstly you’ll want to find a larger zombie with a club on its arm as used during the Hurricane Variant, and lure it down into the Sewers in the Pack-A-Punch room. There on one of the walls is a locker (also seen below) and to open it you have to trick one of the club zombies to run at you so you can run out of the way causing it to crash into the wall and break open the locker.
When the locker is open pick up the battery and put it in the charger by the entrance to the same room. To charge it you have to bring at least two bomb zombies (zombies with massive bombs strapped to their backs) and kill them using the saw trap in the room while they are near the charger itself. This can get pretty tricky and might take a few tries, but just try to look for the green light that will appear at the bottom on the charger if the bomb zombies are close enough for their deaths to count for a charge.
Once this is done take the battery to the morgue and place it in the red-glowing machine on the right-hand side, but before you do make sure you have finished the Lightning Rod quest in the causal easter egg path just like with the other Tesla Gun Variant upgrades. When you place it in the machine you will have to guard it from zombies until a gun part comes out of the center.
After that just take the part up to the Command Room to place the part on the table where you originally built the Tesla Gun to make the Reaper Variant. If you have followed all these steps then congratulations, you now have a fully upgraded Tesla Gun ready for Hardcore easter egg hunting.
