I pre-ordered/purchased it. Mainly to get the Sgt. Johnson firefight character and to get access to the Halo:Reach beta in 2010 and also I sent my flashed 360 into repair it needed to have a reball and unsure if I would get the same console back or a new one I decided to purchase it incase I wouldn't be able to flash it right away assuming it would be a light-on and I'd have to buy the probe.
yo anyone who gets odst add me the game is nuts im playing it right now on legendary if you didnt preorder i susgest you get it tomorrow wen its realeased
