The soldiers starts off at a dinner near a docking area. This part of the base contains the aforementioned dinner, a large crane near few containers and a control room with interactive door panels to secure it. There are four gates that lead to other parts of the base, but they are closed until the vessel arrives.
Upon arrival, every gates open, which allow both soldiers and mutant to aboard the ship, which more or less acts as a bridge connecting to the other part of the base, which is the cargo bay. There's a ramp that leads to a lifted container with a mounted Gatling Gun on top of it, which may prove to be useful for soldiers.
