Unearthed is a symmetrical Big Team Battle map taking place in an abandoned open-pit mine with a giant digger in the middle. The map has a circular layout, but built in many layers like the open mine it is. It was created with vehicle and infantry combat in mind, giving place to driveable roads, wide open spaces and close quarters combat areas. The concept of the map inended to create an infinity loop layout around a big key structure, distibuting the hard action in the middle and the dynamic action outside the inner zones. This map was originally an entry for the Meet Your Maker: BTB Forge Contest, but 343 Industries had another idea for it. On Septmeber 2016 Unearthed was included as an official map for Halo 5: Guardians' matchmaking BTB playlist.
