You exit into a narrow hallway. You spot a stairwell and an elevator. Before you have a chance to make a decision of which to take, you hear feet on stairs and suddenly men armed with guns you recognize as H&K UMPs rush into the hallway through the stariwell. The men are dressed in tactical uniforms, all with a strange red and white insignia. The lead man stops and orders the rest to take aim at you. The leader commands you to get on the floor.
