@Cryo001 It's based off of a "best kung fu moment" video I found, I'm not sure where that specific clip came from but it looks like two dudes sparring in front of a bunch of judges, the resolution looks like it came from the 80's or something. Funny thing is the guy who got thrown in the reference is a lot taller than the attacker, quite the opposite of this Gordon vs CP match up, so you can see the CP's leg almost clip through Gordon's leg in this gif lol.

that looks good and cool

Is this based off of a Mirror's edge animation?

Imagine combat like this in the next Half-Life Can't wait to whack things with a crowbar

Awesome choreography
