My first impression is HELL TO THE FUCK YES
The first think you see in the menu is a person with a machine gun wearing a red bandana and standing next to a bunch of Red/Black posters with cog wheels and labor slogans on them. 10/10 and I haven't even started the game yet.
Update from 3 hours in; this is 100% worth ten bucks. There's a single player campaign and a separate single player STAlKER style sandbox. Lots of fun weapons. Lots of chaotic three and four way battles with ai. Lots of spooky half life and stalker shit going on, a lot of which i've been running the fuck away from because what the actual fuck?
And, critically, you can pet the dog. And bring the dog along as your buddy in sandbox.
