Listen up guys. I am only a 13 year old going into 9th grade taking Geometry. GEOMETRY. Geometry does nothing to help me in this game. However I have figured out with the help of the many comments how to work rifles and jackhammers. For a Rifle, set an alternator valve on the two joint valves, then set the psi to 10. Set a fuse valve under that, and set its psi to 40, no higher, or it will be slow, and no lower, or it won't fire. Connect the boiler to that fuse valve and if you want the ability to control crouching, set a control valve to one boiler using a joint connector at the base of the boiler to have the control and rifle working at the same time. Connect the control valve to the crouch valve and then you can use the lever to control when you crouch. You won't be able to move with just one control, but you will be able to duck and fire like the old geezers used to do when guns first came out.
