all i know is that we are gonna have to fight the flood. In the show Halo, the forerunners got killed by the flood and where going to their planet so is probably filled with flood. We might see dead forerunners "might" because the flood takes over the body. Where gonna see new weapons like the grenade pistol which is awesome. I really hope that the Arbiter is still alive i would love to see him again he's 1 of my favorite characters in the whole halo series. What i noticed 343 industries has the best elites graphic, hope i see the same elite graphics.
