Amazingly, the released version is NOT the version Brat Designs submitted. CDV used a code build roughly 3-4 versions old and modified various things without Brat's consent, creating a worse game. Mighty sad too.
If you can suck it up long enough to get to the main menu you will find a very unique shooter with a mix of squad and personal combat that ranges from ground to air to space. Breed is a refreshing diversion from a game like Halo but its certainly no substitute.
