The map codenamed as "Purple Reign" that is now named Assembly is going to be unveiled today! Although the codename implies that it could be related to the Halo 2 Midship map as stated in the Bungie weekly update. It was also stated that it was purple and Covenant themed. This map may be released with a map codenamed "Space Camp". Which is a Moon Base. No date was set on the release. But we will keep you informed.
