"Isolation"[1] is a map referenced in the Halo 3 Beta code. No information about it has been provided, and it has not been seen in either leaked or official material. As such, its existence is not confirmed, nor are any of its characteristics. Since there are obvious ties in its name to Lockout, it is likely to be a remake.
