KGB is not a very famous game, but it is quite compelling and interesting nonetheless. The story is set a few days before the collapse of the Soviet Union in 1991 and places you in the role of a KGB secret agent.
You start out in your office, where you get to know your not-so-friendly assistant and even-less-friendly boss. You are given a mission briefing and the length of time you have in which to carry it out, so everything starts out very quickly. There is no time to waste. You'll have to get going the moment the game starts and think of what to do on the way. The time limit makes the game a lot harder than it would normally be. However, the real-world setting adds a lot to the playability.
As opposed to most typical adventure games, this one has a first-person perspective. However unappealing this might seem, it actually gets pulled off quite well. It won't take long before you get completely used to it. The storyline is intriguing and will keep you glued to the screen for many hours.
I won't tell you much, just that it is about drugs, the Russian Mafia, and government conspiracy. That is more than enough to keep the missions diverse and interesting throughout the game. As a bonus, there are alternate solutions and outcomes to various puzzles which will affect the overall gameplay.
Viewed from a technical aspect, the graphics are nice, while the sound and music are satisfactory - no more, no less. They're nothing out of the ordinary, but just good enough so that I can't complain about them. Overall, a pretty good game and certainly worth a try.
