Well played. I was playing just for pride by the end there - my original plan had been to ignore the computers completely and just go for kills, but when that didn't work out I didn't have many options besides making a belated assault on the IT after all...
I played as the attacker vs Rabid recently, he completely destroyed me.. I find in the Moonbase missions that it is hard to destroy the computers. It's probably a better strategy to just try and kill all the defenders instead
