How To Upgrade The Tesla Gun | All Variants Guide

There are four elemental upgrades for the Tesla Gun, the powerful energy weapon you unlock early while completing the main Easter egg path. To reach the Tesla Gun, you’ll need to reactivate the power in the bunker, unlock the doors to the Emperor’s Chamber.

For more details on exactly how to unlock the Tesla Gun for yourself, check out the ‘Fireworks’ walkthrough in the link above. We’ll quickly give an overview explaining how to unlock the Tesla Gun here, as well.

Before you can upgrade the Tesla Gun, you’ll need to get the eapon yourself. Once you reach the Emperor’s Chamber, interact with the hilt and kill zombies to charge the transfer device with souls, then travel up into the Command room and turn the crank to open the canopy.

Hit the big red button in the control room up the stairs, and the transfer device will begin to move. Simply kill zombies in the red zone beneath the device to make it move to each corner of the Command room — you’ll get the Tesla Gun pieces. Place the pieces into the forge and the Tesla Gun will be your’s.
