HZD yes. I don't really pay much attention to all the story stuff in games. It's the lowest on my list of interests me.I considered it briefly when waiting at length for the type of PC games I prefer to release. In the end though it didn't look like my cup of tea. A lot of it just looks too weird, like the creatures being a bit too mechanical for my taste. This seems all the more strange to me since the game world and clothing NPCs and the protagonist wear look natural and even primitive. This just doesn't make sense at all.
But I get the general vibe. If you look at the development of robots that's happening now. They are often based on known animals or just their means of movement. The designer for HZD watched a lot of BBC nature programmes and made robot versions.
I can imagine post apocalypse these robots still carrying out tasks, or being reprogrammed by some AI. And the few people left reverting to a tribal lifestyle just to survive.
