Very mediocre.
Writing is bland, it lacks subtlety and the dialogue is hollywood-esque (not how people talk).
Gameplay is just ok. theres nothing here you couldnt find executed better elsewhere but its done well enough.
The visual design of the game is kind of unappealing, same with audio.
The character customization is minimal so you just feel like the same character no matter what selections you make. They also just make it so every path has a way to get through it with any skill so it doesnt really matter what you pick anyways.
You also cant put skill points into specific types of skills, only the general category. So if you want your guy to be really good with handguns but not other types of guns you cant do that.
If you like fallout 4 you might like this, if not you probably wont.
