It took a lot of games and a lot of searching... And yes it's for the recon contest. You can view it here: Bungie.net : Halo 3 File Details Tag mine and I'll tag yours!
Well, I know you're forcing people to go to Bnet to looks at the pic, but I think you need to embed it anyways. And I'm not entering, I've given up on these damn contests. But I'll tag yours. Good luck.
It's a ... strategy I guess. Chances are slim that I'll win, but it's worth a shot. Thanks for tagging.
