Ok, here http://pulse2.com/2012/04/17/conan-obrien-special-halo-4-announcement/

Lol that was pretty great.

It took me until the blue's looked down the sniper scope to realize that was Halo 4 though....looks so much like Reach.

Not bad, Conan voice acting a small role. Something for the fanboys to dissect and speculate over though was the short multiplayer clip, sounded like a suppressed BR. Not sure if that was a Conan sound effect or an actual effect from the game. If it's from the game then I guess it's a form of weapon customization a la COD. One more thing for people to bitch about saying Halo is trying to be COD. I suspect there is a good chance it was added by the Conan crew though.
Gonna go rifle through some Gaf threads to see whats up.

Is there a video up on the web for the Conan Halo 4 segment yet?

I don't know but Gaf has the gif of what was on the show, a short, very short, multiplayer clip showing a BR exchange. It does look good when you watch the gif over and over, some sick shadow details and sparks pinging off of the guy getting shot. Actually, it looks real good, as in amazing. But I'm still mad at you for no officila yet. 

it looks nothing like reach

Frank confirmed on Gaf that the sound of the BR was intentionally suppressed so that you could hear Conan goofing off better. Oh and the awesome multiplayer clip is at the very end of that video I posted above.

Fuck yeah Zane nice gif work. This shit has me even more amped.
