Absolute rubbish. It feels like a test beta rather than a completed game. Great idea, poor execution.
Aiming is painfully inaccurate and too jumpy on medium or too slow on the lowest setting. Movement is very clumsy and feels like you're walking through mud. The sprint function works well, but you easily get hung up on the enviroment everywhere. Jumping is very inaccurate and is necessary in some spots to continue on, which can be troublesome. Climbing and hand over hand functions are nice, but the animations are pretty bad and often you look like you're climbing in mid air, feet away from the intended obstacle.
Graphically it's a disaster. I would say this looks like an early Xbox game. Colors are drab and boring and everything seems to blend together. If this game took place in the trenches of Europe, I can understand muted colors, but in Big City, America, it's unacceptable. Overall, the games looks washed out and character models are ugly. There are plenty of poor animations and graphical glitches as well. Lighting is sub-par, but matches the overall poor quality of the rest of the visuals. This game sorely lacks graphical polish.
The sound is inaccurate as well and with no compass or HUD, it's tough to tell where that last bullet was fired from unless it hits you. Explosions and weapon fire sound dull and tinny. You're no better off playing in full 5.1 than you are through your TV's speakers.
Enemy AI is completely horrible. Enemies will "Hide" in plain site, crouching down several feet from cover in a hiding stance. They will wander back and forth over the same few feet firing, which is that much worse with the terrible aiming precision. You pretty much have to aim at one spot and wait for a moving enemy to cross your bullet's path while being shot at yourself. You will find yourself in several places where 2 or 3 enemy grenades are thrown at you and you cannot escape and end up getting killed. This would be fine (yet still cheap) on a Hard setting, but this was on the Normal mode. Difficulty is all over the place and some spots become extremely frustrating, especially when you notice how sporadic the checkpoints are.
Friendly AI is also a mess. In one scene, you're camped out in a small apartment, picking off soldiers from a short distance when a tank appears. One of your comrades actually slides across the room in a crouching position while the other proceeds to stand right where the tank is aiming, thus getting killed from the blast. Friendly troops are constantly running in front you you while you're trying to fire, but you cannot wound them, which is good I suppose. It takes away from realism, but that's harldy a concern here.
Overall, this game is completely broken, ugly and just not fun. For as long as it was in development, I expected a better game.
Avoid.
