I don't know who Saxton Hale is. What I do know is that after watching this, I think this mod is crap. In just the first match of that video, the red team got in enough hit that he should have been dead more than one time over just from the on screen hits alone, not counting what may have hit him off screen. That strikes me as an intentionally hacked map with either super regeneration or outright invicibility. And if it is the latter, that means that whether it's one vs. the whole red team, or one vs. the whole god damn red planet, it doesn't mean a thing.
This isn't impressive, it's just stupid.
