I’m currently playing through all of the Halo campaigns again in anticipation for Halo Infinite, and I’m hoping to finally nail down which one is my ultimate favorite.
As of right now, I think this would be my ranking, but it will almost definitely change a bit by the time I’m done with my marathon. Also, I have not played 5 yet. I’ll hit that one last before Infinite releases.
6. Halo 3
5. Halo 1
4. ODST
3. Halo 4
2. Reach
1. Halo 2
