This singleplayer story is set in the ruins of an "ancient South American civilization" (a mix of some of them to be precise.
The story is quite simple. Scientists have detected a strong energy signal coming from those ruins and have established themselves there to investigate. Unfortunately they are not alone, and things start going wrong...
The story follows another one of my maps, Vilcabamba. The map has been re-included in the minimod and improved so those who haven't played it see the whole story.
