Maybe your disc was a preowned and the previous owner scratched or something
There must be a scratch on the disc.
Well You should either get another new copy of halo 3, or clean your console.
It is not on a disc! It is on the sheet that says Halo Reach, But you will need Xbox Live.
By getting halo 3 odst ( two discs ) first disc halo 3 odst campaign and 2nd disc halo 3 mythic comes with all the halo 3 maps.
Yes.
Yes
Like i tried Halo 3 but a message came up saying Halo needs the disc but will Left 4 Dead 2 be good to go? I don't want my Xbox working hard on spinning the disc if it doesn't have to, seeing that this is my 5th Xbox... : /
get a new halo 3 disc
sorry kid its done but you should have put in your halo odst disc campain disc and it would say reach reach reach
Yes!, Halo is cool
The same as the one for your Halo Combat Evolved Disc
You have to put in the Mythic disc, then its the same way as Halo 3.
