That giant machine that's supposed to be killing the sun/Yolk. I've tried firing at the central reactor (the one protected by a large shield) non-stop for a good 5 minutes, but nothing seems to be happening. Dodging the large buzzsaw and destroying the homing missiles aren't the problem, but I don't appear to be dealing any damage whatsoever no matter which combination of weapons I use.

Can someone please help me out with this? Thanks!

Nvm, figured it out, the answer was simpler than I thought.
