Put it in the disk slot. Halo 2 is for the original XBox.
No it will only work on Xbox 360. Halo 1 and 2 will work on the original Xbox.
I believe so. Not all original Xbox titles do, but I'm fairly sure that both Halo: Combat Evolved and Halo 2 do.
Yes
Halo 2 was made for the original xbox, unless there was a console before the "xbox" that I didn't know of. It looks cool on the 360 though and Halo 3 looks even beter.
Unlikely. Halo: CE (1) and Halo 2 were on the original Xbox, Halo's 3 and 4 are on the 360, so 5 and 6 will most likely be on the Xbox One.
Halo 1, 2, 3, ODST, Halo Wars and Halo Reach for the Xbox Original and Xbox 360.
Yes, Halo 2 also works for the 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
As far as I know, you can play all original XBOX games on the XBOX 360. It may be different for some of the first XBOX games but both Halo and Halo 2 are playable on the XBOX 360.
Some work like halo 1 and 2
