You hear a loud noise echo behind you. You turn and see a big boulder heading towards you. You run and run but you can't get away from it. You duck and it just misses you. You run into a room to catch your breath. The door locks behind you.
You swing round to try and stop the door, but you are too slow. You catch a lever on the wall. A huge hole opens in the floor and you fall helplessly into deep space.
