ICBM Launcher

This was my second build, just a truck that launches four rockets. Controls are somewhat similar to my tank, driving controls to the right, weapons to the left. The slider to the left raises/lowers the rocket launcher whilst the buttons launches the rockets. The buttons match the rockets IE right buttons right rockets, top buttons top rockets & vise versa for the opposite.

Update 1: as per request and popularity derivatives unlocked. (Sorry it took a while bigdaug)
