1. Halo CE (Amazing campaign and groundbreaking multiplayer)
2. Halo 2 (Good campaign and again groundbreaking multiplayer)
3. Halo Reach (Really good campaign and good multiplayer)
4. Halo Infinite (Really good campaign and really good multiplayer)
5. Halo 5 (campaign was okay, but really good multiplayer)
6. Halo 3 (A lot of people loved it, but it seemed like a remade version of Halo 2)
7. Halo ODST (The campaign was surprisingly good)
8. Halo 4 (I don't consider this a Halo game)
