This is neat. Speaking of apocalypse stuff. Did you see MrSealyP's new series? He's started a new apocalyptic-type series he posted today. It's really cool.
I already have a garage only version. That was initially how it started off. Then i decided to turn it into a full All in 1. I have finished updating the garage only model for the mars 2.0 update. I will decide at some point how to implement the garage only placeable. In a future update for it. I already have some ideas. But it will be some time as I am very busy with other mods.
