Ok, I'm about 50 hours into the game and last night I found the Euclid C-finder weapon. Turns out you have to have it with you at Helios one when you do the "That Lucky old sun" quest to arm it with the acrchimedes ammo. I looked at my save before I activated the Helios power and I was at level 8 where I'm now around level 26. My question, is there another way to get ammo for the Euclid C-Finder or am I out of luck? Or should I be able to go to the Helios "area" to get the ammo (I've tried this many times). Or is this simply a bug in the game? Any help is greatly appreciated.

That has to be a bug. Cause once you run out of ammo or w/e, you'd need to return to recharge it.

Wait what? In order to use the C Finder you have to route power to the Archemides instead of the power grid. Then you will have one charge and it takes 24 hours to recharge after you have used it.
