The Goliath Prototype is exactly what it's name entails, the first of the Goliath cyborgs. It is composed almost entirely of metal with a synthetic-organic composite added to the mix. It's back is mounted with two mass effect generators which give the machine biotic powers. It is also equipped with a mass accelerator machine gun on each of it's gauntlets. The Prototype itself is very strong and incredibly agile but it's balance is almost entirely depended on it's mass effect generators.
