If I were you I would praise Jesus, Alah, Jahosephat, Virgin Mary or what the F^%$ ever that your disc doesn't work. Its just your god telling you its ASS. Reach is the second worse game ever made next to dragon age 2. Halo 2 was the best in the series, halo3 was fun then somebody said "to hell with halo and the true fans lets appease the 8 year olds" and odst came out. Reach is the biggest piece of sh^7 to come along to a great series ever. The story is garbage, the matchmaking is slow and atrocious. ITS HALO 3 DOWNGRADED IN EVERY WAY EVEN THE ARMOR ABILITIES IS A DOWNGRADE THAT TAKES AWAY FROM MM PLAYABILITY. I don't want to admit it because I loved halo so much but the series is dead and bungie killed it.
