It has been asked so many times.
Halo - Has a great Campaign and great graphics for its time. 9/10
Halo 2 - Has a fairly good Campaign, the Multiplayer and Xbox Live make up for it. 9/10
Halo 3 - DOMINATION!!!!! 1000000/10
I think I seriously made my point.
i disagree i think that halo 1 has better weapons than 2, but halo2 makes up for it with alot of stuff, and that halo3 is r d
halo1 and 2
wats so bad about halo 3? you get a good multiplayer, good graphics, an actual award for collecting all the skulls. and halo 2 had an ok campaign, you get to be arbiter and MC, also the introduction of a few cool things, energy sword, scarab, and... brute shot (an excelent gun in my opinion). halo CE had good graphics for its time and as usual, a good campaign
halo CE- 9/10
halo 2- 9.5/10
halo 3- 10/10
