Hey, I have 2 questions. Assembly machine is almost impossible to make without an assembly machine, so how am I supposed to get red copper or whatever it was. Second question is I cant get the radar system to work. It doesn't take power in, and I have no clue how to link a nuclear reactor to it. Also I have seen that its possible to shoot down a nuke with 7 phalanxes, but not sure if it works. Also if its possible, I would want to know what blocks do i need.
