Tough Luck and Catch on! Anyone else absolutely love Firefight if you played Halo!? I don't even know what "The Arena" holds in store for us but I played Firefight so much, even in ODST when there was no custom options. Bungie says the aim is for The Arena to add more replay value to the game and if it's even half of what Firefight was but with gear and engrams as rewards then sign me up!
