A above average game with a deep story line. Even if you never played the first one i would recommend you trying this game.
Graphics: There are a few glitches and game does tend to freeze up ocasionally but the graphics are superb and very lifelike.
Gameplay: A good mix between stealth and just running into rooms shooting. You can pretty much decide the way you take out the enemy if you want to be stealthy you can or just bounce grenades off walls into rooms. The game tends to be addicting and is relativly short i completed the game in less than a week. Although it is short the game is well worth it for its story line.
Controls: Fairly basic controls not hard to master at all. The one thing the game lacks is the ability to switch weapons quickly which can hurt you in tight and close situations and when you run out of ammo.
Lifespan: I find that this game has hardly any lifespan you buy it, beat it, and thats it. Although once you beat the game once you unlock a couple new game modes they are basically the same thing just a little harder. If you could make your own decisions during the storyline of the game I think that this would prolong the games lifespan.
Final Note: I think that this game is overpriced at the moment for $50.00 I believe you should get more. The game is way to short for the money it costs. Even though it has a high cost i would still recommend you buying this game i would just say try to buy it used.
