Ah, the Kazakhstan ending. Firstly, you cannot kill the creature so don't bother shooting it with your weapons.

There are levers on 4 sides of the large circular room you're in. Roll, dash, and dodge the demon's attacks and pull each of them down. You will then be able to use the Tesla coil in the center of the room. Get on it and blast the demon into the electrical current running across the walls. The demon will be dazed shortly, giving you time to execute the next maneuver.

You need to use the Tesla coil to push the 4 large orbs towards the small electrified orbs. To do this, press your shoot button repeatedly. Two or three shots should be enough for each orb. Repeat the same for the 3 remaining orbs as quickly as you can, because they'll reset to their original position shortly afterwards.
Once all 4 orbs are pushed, get off the Tesla cannon, look directly up at the sword fragment above the coil, and use your grapple. Lara will grab the fragment and trigger the ending cutscene.
