I had an eye on this game someone mentioned something about an earthquake that destroys all their hard work on the base have you come across that?
The maps get to be huge so even though a comet can technically hit your base too, things are pretty rare. Meteors showers are everywhere though. I'm loving the game and wondering how much more of the planet will open up. Regardless of building big or spread out, the more you build the bigger the reaction from the environment/wildlife.
My final thought is if someone wants to wait for a minimum of 30% sale, that would be good. I'm glad I got it early at a 15% sale though. Worth the $27 for flashy destruction and random intense chaos with a base builder/tower defense play? People should check it out.
