Nomads are in! I've also finished the sprites for the Bretonian and Gaian ships!
To emulate the tentacles, I've given the Nomad ships some external engines. Looks a bit weird, but they react to accelleration and to the Plasma Engine ability (everything turns green). The Nomads don't use shields (like in vanilla) but have long range beams. Their first wave of hangar pets is devastating, but once you're through, you should immediately take care of the capital ships.
