Captures from September 25, 2008's CG teaser, "Keep It Clean" featuring the Superintendent and apparently set in or near New Mombasa prior to the events of Halo 3.
00:36 The super's trademark "Keep It Clean" also appeared in the mess hall of the PoA in Halo 1, and was interpreted by many to indicate that the protagonist(s) of this title will be marines, not Spartans.
00:36 Final notice, bill past due. Perhaps an indication that the Superintendent is no longer functioning at full capacity; such a mundane message is otherwise inappropriate for an emergency situation. Is it a reference to the changed relationship between Bungie and Microsoft?
00:36 Danger: Flood Zone. If this is Mercy's departure the Flood won't arrive for some time, but the time period to be covered in this scenario might stretch from the end of "Metropolis" in Halo 2" at least as far, if not further, than the start of "Floodgate" in Halo 3, remaining on Earth. That players did not get a chance to fight more often on Earth was a common fan complaint about both Halo 2 and Halo 3.
00:32 After several seconds of black screen this Superintendent screen appears and displays several consecutive messages. This one is "PLEASE REMAIN CALM" but in Russian. The previous one was in Spanish.
