Looking for an interesting 15-20 hour stealth action Cold War title then you’re looking for Death to Spies 3 coming out of 1C Company Spring 2011 for PC and Xbox 360. In the meantime you can catch up with our intrepid main character in the first two titles. 
In Death to Spies 3 you’ve moved your base of operations over to the US and are skulking about being the typical Russian spy. That includes things like assassinating traitors, obtaining information, picking locks and stuffing bodies in big red wardrobes...whatever would we do without those big red wardrobes?
The stealth action is broken up now and again by lockpicking and some clothing changes (prior to stuffing those dead bodies in the wardrobes). The game has some elements that have now become typical of the genre including spy vision which gives you information on the NPCs around you like who is on the lookout, who is alerted and who is a non-issue.
Since it’s the Cold War and you’re a Russian Operative behind enemy lines (within the lines of the US) you will need some serious gadgetry to get by. Luckily, they’ve taken some real-life gadgetry, Bond wizardry and mixed up a healthy batch of exactly that.
