Honestly, I said it before (when the game wasn't out yet and they were showing screenshots). The setting is fine, the execution is terrible.
The visuals are clashing so hard, it all just looks wrong even till the end. The textures of grass and plants looks like it was lifted from Risen without changes (bright, looking like fantasy setting grass) while buildings look (most of the time) pristine and lifted from some Unity Asset store package. It's obvious they were trying to get on the Fallout 4 money wagon but even Fallout 4 has better visuals than this. Even the trees selected for this game are all wrong (needed different types of trees and variations).
The worst part isn't even the environment, it's the armors and weapons of the enemies. They just don't feel like they belong together and look like generic fantasy armors.
It feels asset-flippy at times, yes. Seeing super flashy, unrealistic sci-fi and fantasy stuff put next to literal Hummers and Peugeots and the gas station down your street can either "click" with you or give that effect. Plus, it makes the world feel weird or not very well thought-out, since what is for all intents and purposes a real-world western civilization got apocalypsed and decided to start LARPing, but was still able invent laser weapons, gravity-defying gunships, or freaking magic (I know,
a wizard Elex did it) after the end of the world.
