Simulation of UNSC Training Facility Bravo, more famously known as "The Pit", which was destroyed during the Covenant glassing of New Mombasa and the East African Protectorate. The simulation has adapted the training facility in order to conduct tests on the recently introduced thruster packs, now included with every Spartan armor variant.
