halo 3 duck hunt?

[trunolimit]

I played this game variant called duck hunt where ther is a sniper and everyone else has to duck for cover. has anyone else played it? if so how do I get it. I also want to know how to get the jenga variant and other variants like that. I'm on the xbox 360

OK so a whole lot of digging and I found out that I can go to bungie.net and download custom game variants and maps to my xbox360

Any certain ones that you tried that are worth downloading? There is a lot to choose from.

Does it have a dog that giggles at you every time you miss?
