I found the FiendMK2 fairly structurally sound, and if I had a better computer, I would have tested several angles of fire. However, I managed to do a fair amount of damage just by letting loose the entire armament of one of my cruisers. Main points: It is weak to fire in the front and back, especially with the engines cornered in like that. Consider a new kind of cover. Sides are strong and sturdy.
