AC Grim BeastEdit
Quad-leg AC model equipped with an abundance of hard-hitting weaponry. Close-range attacks using a grenade launcher are its forte.
This AC is tough enough to eat nails and ask for seconds. Impressive firepower combined with thick armor makes this a hell of a fight. Unless you think you can dodge him in the tiny factory you have to fight in, your only other (wise) choice is to try and outclass him in firepower. Build a tank based AC and get the toughest armor you can. Then add the large apeture cannon and a plasma rifle on the left arm. Once the battle starts, charge at him and let loose with both weapons. You're gonna want a high quality generator and maybe energy extentions as well.
