Its just a repackaged Deep Stone Crypt. Appears to be what remains of the spaceship we destroyed in DSC, with lots of damage & debris. You use Scanner and Operator augments to shoot keypads & break into the ship. First encounter has no real boss, just deposit nuke cores into bins & damage the system (like 3rd encounter DSC). The second encounter adds Suppressor buff, more keypads & a huge servitor boss surrounded by a gang of mini-servitors. The meta-strategy here would be hunter void tether, but of course Bungie disabled that specific super for the WHOLE dungeon. In the 3rd encounter, there are tons of Atraks copies & you use scanner to figure out which is the correct one (again, just like DSC).
