Godzilla

[gogeo]

I think it will be fun to have from time to time Godzilla beast comming out and destroying colony. It will help in many ways:
-force usage of roboport
-better defence
-more fun for long term games
-in future player can create mecha-godzilla and send it to fight against it or to other players - mod gvg (Godzilla vs. Godzilla )

Have fun
