Halo 2, its better in almost every aspect. except for the gay pride van. (also known as the alien warthog thing.)
Ive Played Halo 1 the other day and then Halo 2 there is so much of a different Halo 1's Graphics are less detailed than Halo 2's. Same with everything. Halo 2 no doubt
Halo 2 is better. u can play online and ther more new weapons. campaign mode is cool and there is alot of new features
Is this just spam or what? Its obviously Halo 2. Youre probaly just trying to get credits / post count. Halo 2 by far. Best game ever. The only bad thing is short campaign. And btw, multiplayer / online is on both Halo and Halo 2 =P. Halo 1, you must enter some cheat or something to play online =P.
