Ivory Tower will become "Reflection" and is as close to a remake as you are going to get, with minor changes to fit Halo: Reach's physics, according to IGN. Midship becomes "Zealot", but will be going through a major change in the transition, gaining a third level of elevation that takes place in space, complete with low-gravity.

Spire, a third map new for Halo: Reach, has also been revealed for the game's Invasion gametype. In it, Spartan players will start on a beach assault a giant Covenant tower in this vertical map. All three maps can be seen in video form at IGN.
