So, I've been thinking of starting a Winter Survival map. The idea of the map is that it will be divided into several areas. The first will be a flat plain with the remnants of a ranch on it (Burned down/ abandoned huts, hay bales, etc.). To the north the plain will drop off into a rocky canyon. To the southeast is woods, and a cave system. At first glance, this will look like all the map is. But by going through a secret entrance, you'll see that there's an old underground research facility below the whole thing.
I would appreciate ideas for a name, or other things I could implement in the map. I was thinking one of the entrances would be accessed by breaking through a wall in the cave. The research facility could contain controls that influence the land above, like draining a river, or blowing up antlion hills and trees. Maybe there could also be a specimen room that contains specimens of antlion hills, rocks, trees, and water, but can be destroyed from another room, or 'decontaminated' (sealed off and filled with deadly gases) in case of a dangerous virus being found in the specimens?
So, those are my ideas. Tell me what you think I should put in.
