I enjoyed the character writing a lot and the overall story arc was interesting. The quests could be challenging without being too grindy or obscure, but the moment-to-moment gameplay was... just ok? It felt even clunkier than Fallout 4 in terms of how an FPS plays..
The maps and environments looked good but were pretty generic in terms of layout and variety.
I don't regret buying it (on sale), but I haven't picked up the DLC, and probably won't.. I had my fill with the base game.
