After finding the entrance to a secret network of caves, you have dived into the bunker in order to avoid the goons who are looking for you above. You have a LED Flashlight so you don't have to worry about being in the dark, so now you can find out where this network of caves lead. This game uses the cursor keys for 3D navigation. Up moves you forward. Left and Right turn you left or right, and down reverses your direction. You can pick up items by clicking on them when you are close enough and can go through a door by walking into it.
