yes you can also play it on your PC
You can play halo 3 on any xbox 360.
No, you do not need Xbox LIVE to play any original Xbox games. Not all original Xbox games can be played, but Halo and Halo 2 do not need LIVE to be played on the Xbox 360. I just now tried it with my LIVE unplugged and signed in to an offline account and it let me play both of them. The previous answer was a lie, obviously.
Yes, but only to play system link xbox games that are compatible on the 360 (like Halo, Halo 2 and the like) but not to play system link on games that are on both (Battlefield 2 Modern Combat) using one 360 version and one Xbox version
No. You can play Halo Reach on the old Xbox 360 consols.
You cant its not an online game. But Halo 2 is and you just hook an ethernet cord from the back of the xbox to your computer modem.
Halo 1: Xbox, Xbox 360, & PC Halo 2: Xbox 360, & Windows Vista Halo 3: Xbox 360
Yes you just have to get a free update off of xbox.com but you might have to search under something like original xbox games. After you find it you have to put it on a blank CD and then just go put the CD in your 360 and update it.
Yes, but only over Xbox LIVE or through system link. You can have up to two people per Xbox if you are playing campaign. The same goes for any Halo game except the first two (you can't play their campaigns over Xbox LIVE, but you can system link)
No, halo is exclusive to the xbox 360. The xbox will be the only console to ever play halo on.
No you need the hard drive and xbox live to play xbox 1 games
You can play 4 player co-op on Halo 3, but not all on the same Xbox. To play 4 player co-op on Halo 3 you can either have 4 people all on different xbox's and use xbox live, or have 2 people on each Xbox and either use Xbox live, or System link to join the parties together.
Yes you can play Halo 1 on your Xbox 360
