OGame Japan

表面と地下 - Surface and Underground

We will have this tags:
Diameter: 12.756 (0/196), this already exist.
Underground: 12.756 (0/196), this is my suggestion

I believe, with this suggestion, the new build "hideout" can be more effect and a lot of future new builds and research can be developed for underground.
Well, can be develop a new commander with special features for undergrounds and increase the strategies capacity on the game!

Requriments: not, because each planet have underground and surface from the beginning!
Positive Effects: Make the game much more strategic and a lot of a new possibilities can be develop.
Negatives Effects: No.
