1. Halo 2 2. Halo CE 3. Halo Reach 4: Halo (3) [b]ODST[/b] 5. Halo 4 6. Halo 5 7. Honorable Mention (Halo 3) [spoiler]My favorite part is the Mausoleum of Arbiter fight with Breaking Benjamin song, the song added extra epic feels to the fight. (Good ole new-rock). Halo CE was fun, I liked the dark horror story intro to the Flood. I will not rate Halo 3 here, reason is it took forever for me to get an Xbox 360 and by then I picked up Reach and 3-ODST. Reach was cool as it added a sense of realism in that Spartans can die, also custom armor. ODST was just fun, felt like a sneaky Black-Ops kind of Halo take. After tons of playing other Halo's, Halo 3 felt kind of bland, the whole Flood part felt long and boring, the pistol felt wonky, story only really got good at the end and the warthog drive.[/spoiler]
