Continuing from Episode 7, Randall fights his way through Covenant Loyalists and Guardians to destroy Avalon. But as he races to accomplish the task, he finds himself thrown against his enemies. And this time, only one will walk away.

This is the last full episode. The next one, 9, ends the series but it's VERY short. No promises on when it'll be released, but definitely within a week.
