port infestation

Your at work with 2 of your work mates when the port sirens go off, the boss runs into the room and tells you that one of the containers that was labled as toxic split open 10 minutes ago. He carries on to tell you that a few workes that tried to clean up the mess got infected and 3 minutes later they started attacking every one south of the port. The authorities have now quarintined the port the boss says....the only way to escape is on the ship, we must get to the ship and cast off!!!
