A while back I played on a foundry map which was a circular arena with a game type designed for practicing racking up as many headshots as possible. I can't remember the name of the map and I can't find it anywhere. Anyone know where I could find a similar map? (And yes, i've searched fileshares on bungie.net).
octagon or BR pit you will find those on Bungie.net : Developers of Really Cool Stuff just type them into the search bar.
