For more than a decade, the hapless, helpless and occasionally hopeless anti-heroes of the Halo universe known as the Reds and Blues have fumbled their way from one adventure to another. They've survived aliens, Freelancers, evil artificial intelligence programs, and secret government conspiracies. But now that they have been shipwrecked in a mysterious canyon, they will have to work together to survive their greatest foe of all... Themselves. Yes, once again the misfits from Blood Gulch find themselves stuck in the most worthless piece of real estate in the galaxy, or so they think. When dark forces begin to align against them, they begin to realize there's a lot more at stake than just being rescued. And this time just to survive, they might have to do what they do worst... Fight.
