My idea revolves around a world involved in a huge war between colossal
machines. This war destroyed almost everything, and centuries later civilization is still recovering. Mining colonies are being set up to salvage resources from the relics of the old war. This is one such colony on a severed hand of one of the giants floating through space.
The blockout so far in UE4.
Buildings you can see are placeholders just to show that there is a small collection of buildings surrounding the mining tower in the middle. I don't want to make this a huge city or anything, it'll mostly be industrial/storage structures with some living quarters and offices. Essentials such as food and water will be shipped onto the site as the primary reason for the colony is resource extraction, rather than to set up a self sustaining base.
