Inside Mike Young's Room (Revelations, Diplomacy, and Terror!)

From the introduction: You are part of an expedition to explore the Lost Tomb of Zeyxx. You were just wandering around when suddenly this monster awoke and started to chase you . Your guns proved ineffectual, but you have managed to hide in here and wedge the door closed. While this will buy you some time, it won't stop the monster and eventually it will break in. You're trapped in here. What do you do?
