(You would be inside the great underwater city of rapture just making your way around trying avoid splicers, all you're armed with is a dinky rusted snub nosed revolver, when you make it to a large empty atrium room with a good window view of the rest of the ocean and rapture. Suddenly you hear a loud ear piercing screech, its so loud you cant tell where its coming from, you try to grab your revolver but it breaks in your hand, then you see a glowing red light in the corner of the atrium room)
