Halo: backtracking

Sort of backtracking, at least. I've decided to try and finish this over the next few days since Tam's going to be busy writing her dissertation. Some pleasing progress tonight, past the big outdoory snowy bits and I'm now back to the corridors of the covenant ship that you get beamed up into from Halo near the start. It looks like I've got to try and get back to places I've already been, but the ship's been blown up a bit and rather than just covenant enemies, there are the flood as well. I've already watched some pretty spectacular battles between flood and covenant - watching from afar so that I could just take on the survivors - normally flood. The shotgun is my friend.
