Orbital

Orbital, also known by its former names, Moonbase Alpha and Space Camp is a map that was revealed in Game Informer magazine of December 2008. . It will be available for download on Xbox Live Marketplace in a future DLC release; however, Orbital along with Assembly and Sandbox have been confirmed to be shipped with the Limited Edition of Halo Wars. Bungie has confirmed they are working to get these maps available on Marketplace as soon as possible after Halo Wars' release in February/March 2009, but a specific date is unknown. The release date for the other three maps is also unknown.

Orbital takes place on Quito Space Tether, a huge tower that transports cargo and people in and out of the atmosphere easily.

It is said to be best for asymmetrical objective games, like CTF and Assault, but also has some natural deadlocks that makes Slayer interesting and Infection "terrifying". The map consists of two hallways overlapping each other. Both bases of the map have openable doors that are crucial for objective games. . There also appears to be at least one stairway.

The map is located on an "empty UNSC space platform", more specifically, the station atop the Quito Space Tether. The map contains plaques dedicated to Doctors Tobias Fleming Shaw and Wallace Fujikawa, the creators of the Shaw-Fujikawa Translight Engine. . One part of the map has a deadly chasm, which can be easily traversed once it is "unlocked". This could mean that part of the map is in the vacuum of space. Orbital has several such locks and "switches to disable and enable access to various parts of the map". Orbital has been described as cleanly beautiful, yet haunting and having signs of abrupt abandonment.

Skull
The logo of the hidden skull on this level appears to have a symbol that looks like a giant fan which could refer to be a Orbital Defense Platform or a Mobile Station like the UNSC Cradle or the Station Delphi.

The crest of the hidden skull on this level appears to have a symbol that looks like a giant fan which could be referring to a Orbital Defense Platform or a Mobile Station like the UNSC Cradle or the Station Delphi. The skull also resembles the Cylon Base Stars from the television series Battlestar Galactica. The symbol on the Orbital Skull also looks somewhat like the Forerunner Dreadnaught.
 * The fact that there is an achievement to score 2 Death from the Grave medals in a single match online suggests that the map will have tight quarters and small rooms.
