Hall of Infinite Doors

You know that you dont want to fall to your death, so you pull the cord almost immediately. A black shroud raises above your head and you drift down to a beach. You hit the ground quite hard but you suffer no injury. You pull of the parachute and hear a beeping from your bag. You reach in and pull out a radio and hear Kaya's voice. "Oh, good, you landed safely, advance up the coastline and make it to a security station. Kill any guards you find there and contact me again, good luck."
