Repository

Repository is designed to be a 2v2 map, most likely set on a Forerunner world or construct.

Layout
Rather than being occupied by the usual Rebels, the four possible base locations are held by equally powerful Forerunner Forts, which are protected by Sentinels, laser turrets and a solid-light barrier/shield. Other Forerunner elements are spread throughout the map, including a Sentinel Factory located directly in the center of the map on top of a large circular Forerunner structure, linked to the surrounding land by four Forerunner bridges.

It is understandably common that many players will fight over the center of the map for this Sentinel Factory. Also, there are sentinels randomly placed around the map (meaning not defending any structures), that will ambush any player's units, which may slightly hamper offensive operations.

Trivia

 * The circular area of the map is an obvious reference to the one found on the popular Halo 3 map, Guardian.
