Just picked up this game on a recent Steam sale, and I have not been able to put it down! Best game I've played in a long time. Open world with everything from scouting and planning your missions, to taking whatever approach you feel like in solving the task. I think the only thing I don't like about it so far is the "bossfights", as they haven't really given me as much freedom in how to complete them.
If you like stealth/sneak games or 3rd person shooters, you should definitely put this game on your wish list for the next season sale, or just buy it straight away, depending on your wallet and interest.
Anyone else picked this game up?
