One of the earliest Resonants you’ll fight in Control Resonant is the Central one. It’s hidden inside a locked factory that has plumes of smoke pouring out of its roof. To reach the boss fight, you need get into the Central factory in Control Resonant, which is easier said than done.
How to get into the Central factory
There are multiple doors on the outside of the Central factory, and you need to be careful of the pipes as you explore it, as getting too close will lead to an untimely death.
To get inside, you need to go through the door at street level on the right side of the factory. That is on the right side if you’re at it from the front where all of the vertical pipes are.
Starting at the front of the building, where the tower of six electrical boxes is, attack one to electrify your Aberrant weapon and sprint as fast as you can to the right side of the factory.
If you can avoid all of the Hiss roaming the streets, attack the electical switch on the wall there to transfer the charge from your weapon to it. That will cause the door next to it to open, so head inside.
Even if you manage to avoid the enemies outside, you’ll be shut into the area inside the factory, and will immediately have to fight a wave of enemies on your way to the tricky Central Resonant.
The important thing, though, is that you’re inside the factory, where the path to complete the quest is easy from this point.
