God Rod is a space tech that is mounted on a space platform. It can be researched for 10.000.000.000.000 GC and mounted on a space platform for 10.000.000.000. They can destroy Primitive and Avanced moon colonies and mines, but not Moon Command Centers and superb colonies and mines. It isn't as effective on earth (functions like a normal bombardment).
God rod is based on a future space weapon, the Rod from God.
