I must say, the missile bombardment for Prime is just so unrealistic. Not in that we wouldn't load up missiles to a satellite, hell, the only thing that prevented the Russians from doing that with nukes during the cold war was a little piece of paper they signed making it illegal. No, what's unrealistic is how weak it was. COD Ghosts came out, and the Kinetic bombardment would not only have caused more damage, but would have been legal by the outer space treaty preventing nukes and missiles from going up on satellites. Now, I did the math (meaning Game Theory did the math and I double checked) but a 6 meter long, one foot wide, missile of Tungsten, falling from space, not even having explosives set to go off on impact, would have obliterated Prime and destroyed the nearby facility where they triggered the barrage.
The fact that a barrage was needed to destroy prime was absolutely pathetic, ineffective and illegal. When the legal option is much more powerful than the legal one... You can't justify that in a war. Say it was a nuke, well then, I'm on board for that having been used against Prime. But it was some weak ass missile that didn't even completely destroy the robot or tear up the ground.
