From Halopedia, the Halo wiki
The map is a symmetrical map that is set in a Forerunner databank which is entirely set into a cliff face. It is reasonably small, consisting of two bases, each with four tunnels leading out of them. These tunnels emerge on either side of the map, in two large rooms, which are essentially reflections of each other. On one side, an Energy Sword can be found, and the room is open with a view of several waterfalls descending into a chasm, above which the map is situated. The opposite room contains a Gravity Hammer and two Type-50 particle beam rifle, and instead of a landscape, its view is of the databank, maintained by flocks of Constructors.
The Constructors on this map are capable of being destroyed.
