Game originally worked fine...
Once I go up to the space-flying stage, the stage loaded, and game was about to start, then got disc read..
A select amount of multiplayer maps worked, others randomly worked, and a few space-themed maps haven't loaded at all yet...
Installing to the hard drive gives a green screen before the opening cut scene even starts, giving no access to the main menu, and when running off the disc, only the main menu works.... no game modes load what so-ever...
The disc itself works perfectly on all other Xboxs that I've tried.... it only gives errors with my 60GB Elite (Grey Tray)
I can't be bothered using my money to buy the new slim, just to play this one game....
Halo 3 and ODST can be played by keeping the save game and profile on a USB stick, but reach doesn't work, and most modes often need a hardrive anyway....
Not impressed...
