I was really not excited for Halo 5. I enjoyed 4, but I was asking myself, do we need another Master Cheif story? After I saw the Hunt the Truth trailer, it peeked my interested. Why are Spartans hunting the man, or in this case, the weapon that defeated four world-ending events?
Then the Hunt the Truth podcast came out. This podcast was fascinating. It really questions the lore of Halo.
