Capturing the accelerator

Hey there I could use some help with capturing the accelerator with the marines. I can't seem to target the correct pieces in order to disable the shield. Canone have some insight into what I might be missing.


Born a century before my time.

fly into the accelerator.
inside at the middle you see 3 (or 4 dont remember) white points these are the generators.
Use zoom to get a better view at them.
And destroy them with some beams, remote missels work too, but you better fly out befor you fire them.
