Submachine: ExtendedThis is exactly like the Submachine: The Basement, except this time there are many more chambers and many more tricks to it. You have to move around the chambers, finding different objects and tweaking different objects to perform particular functions. As you find various objects you have then to find the place where to apply them, once you do they will enable you to do more on the level. Move around collecting items and hopefully you will be able to escape.
