A fairly large expansion pack for BZ2. Includes 14 new single player missions and an entire new human faction known as the Queens Filchers. Battle across the solar system in an effort to protect your turf from the Hadean and Cerberi invaders, while making sure you stay out of the way of the EDF and Scion forces as they defend themselves from the invaders.
A very well made mod, had a real blast playing through it, and incorporates some very refreshing ideas.
I'd highly recommend it if you haven't played it yet. Make sure you get the patch too.
BBB, I'd recommend uploading a download to this page as well.
