I've made it abundantly clear how much I enjoy the Halo franchise. I practically jump at the chance to mention it whenever I can, and because of that, I was always disappointed that I never got the chance to properly play Halo: Fireteam Raven.
For those unaware, Fireteam Raven is an on-rails arcade shooter set during the events of Halo: Combat Evolved. Players take on the role of a group of ODSTs, starting you off aboard the Pillar of Autumn, the same ship where Halo: Combat Evolved begins, and then proceeding down to the Halo ring.
