Uhh Halo Rings can use Slip space, Umm Also Primordial. Also Precursor. Also Shield worlds. Oh The Didact, Cause he's a boss ass commander. Also suicide grunts GO. Na It'd be a good fight If Super weapons didn't come in. Then Again the flood could just infect all the Clone trooper dead bodies and Halo casualties and just have a hay day then end up turning on everyone cause they be a boss ass bitch.
