(its Doom 3 all over again... advanced futuristic mecha death weapon with no IR or Lowlight vision modes... and there's a full bloody moon too, so 'its too dark' just does NOT cut it.)
I used a single moonlight blade setup, geared toward keeping my energy for maneuvering. Slice at the back or top of the fortresses where they have no guns. Practice on the initial fortress to get some techniqe of getting into a position to slice them. If you take a hit from the first fortress, you can probably forget about that run. You can also try adjusting your tv settings to decrease the contrast and lighten up the screen. Keep at it, you'll get lucky on a try and nail it. Personally, the kojima cannons were utter fail for me.
Have you done Ascend yet? That one is a beast too. Three fortresses while ground based cannons shred you.
