I guess I'm just too used to this but for someone who's unfamiliar with this yeah it may look so. Although it's incredible how those wiggles (strafes) can differ. Some guys are so smooth which makes it for aesthetics at all fullest, within enlightened range of course.
And btw it's not cs defrag, not even kreedz, it's hns (hidenseek), terrors are set to stab ct. It's probably as old as kz but has progressed really a lot. I know you guys heard a lot about jumping but I'm almost certain this shit is new to most of you.
I've been playing quake for all I remember myself and a little bit less in jumping, I'm considered as pro kzer (got many youtube videos, world records and shit), but I never managed to learn hns. I say this is the hardest game I've seen so far to learn and understand physics to then use it like this guy.
