I was hooked by the premise...i'm a sucker for secret soviet projects in the 1960's and 1970s. The graphics are great and the storyline lets you have just the right amount of info to keep it interesting. For an adventure/puzzle game thats not fully open world, the devs have really done a great job, I'm still in the middle of the game, taking my time to explore. I havent bought a game for a few years but I'm glad i picked this up. It can be finished in likely as little as 10-12 hours but easily rewards players who want to take their time to really inhabit the in- game world...and at this price, its' a real bargain. I highly recommend picking this up - you won't be disappointed!
