Not my usual Cataphract build here. Ultra Autocannon? XL engine? Pulse Lasers? Probably not a particularly viable build in-game, more of a showcase Mech the Capellans might have built. Possible usefulness as a flanker.
Why make it simple when you can make it complicated? More than the XL (I use it on most of my phracts), more than pulse lasers, what's bothering me is the four weapon groups.
