I am shocked. Not that the servers are shutting down, but that the servers even existed in the first place.
From the moment I saw the first trailer I thought a few things:
First, the concept seemed cool. I don't like zombies and find them to be very uncompelling as an enemy type for various reasons, but to me the trailer seemed to show a game that was like if Project Zomboid played a bit like The Division or Ghost Recon. I never played The Division, but I have put a lot of time into Zomboid and many Ghost Recon games over the years. So the concept was incredibly appealing.
Second, the trailer looked 100% fake. That's not to say that the assets didnt exist or anything, but rather it felt like a mobile game ad, where the trailer "gameplay" is way better than and completely different from the actual gameplay.
All in all, its impressive that the game actually existed, but it would have been better if the developers delayed the game (again) to keep working on actually making it function decently. And maybe making some original assets for it instead of purchased ones being used almost directly out of the box with minimal if any modification.
Where they really expecting a positive experience for gamers when they released the game? Did they really think that players will stick with the game that has so many bugs and lacking a lot of features?
