Excellent 60s atmosphere and addictive gameplay combined with cool colorful graphics makes this game an instant classic.

User Rating: 10 | The Operative: No One Lives Forever Game of the Year Edition PC
This game presents everything a gamer expects from a stealth FPS;
- Easy to learn, yet challenging gameplay : Its playing style doesn't differ much from classic FPSs; but with the help of the clever-at-times AI and carefully chosen range of arsenals you can use, it provides the gamer with a unique style of play which holds on to you until you beat the game.
- Good story : Don't expect an incredible storyline with unexpected twists and extremely deep characters, they're not present in this game. But the game's story is more than enough with its cliche plot twists and some foreshadowing to provide support to its atmosphere.
- Cool graphics : The only flaw about this game's graphics to my opinion is its crappy character textures. The tastefully chosen color palette of the game which focuses on orange and other pastel colors does a great job to strengthen the 60s atmosphere.
- And finally, incredible atmosphere : You'll see that I used the word atmosphere a lot of times in my review, because it is the most powerful aspect of the game. Everything in the game -from east Germany science facilities to humorous dialogues between enemy NPCs- adds up to the atmosphere and makes the player breathe (a little exaggeration won't hurt) the sixties.
Overall, this game is a must have for every PC gamer whether or not he enjoys FPSs, its uniqueness and extremely powerful atmosphere makes it my favourite game of all time, and hopefully yours too :)
