Yeah, bungie was sayin' that if there was enough demand, that there would be a sequel, highly doubt it, but it's entirely possible. I would want it to be about the same group, just you don't have to go around looking for each other, it could be about various important ground fights in the defense of earth, one mission you get dropped right into the heat of battle, like u walk out of ur pod and start killing immediately, and you could control where ur pod lands too, and get a splatter if you land right on top of someone, then after the battle, you would move on to the next mission which would be a really stealthy dark sniper setting where you have to snipe some important covenant leader or something, then to escape, you have to board a phantom, and this time you actually get to fly it!!! Then in the next mission, you have to destroy a scarab factory, like in assembly, you have to sneak past a couple of scarabs to get inside, then lay charges on some generators, it'd be a close range mission, as you fight your way through the facility, that's about all i got
