The game's not hard, and you have enough time to aim for enemy's heads, although this is not necessary as you can put them down even with leg shots, it really doesn't matter. Also, you can reload with the space bar as much as you like. Even that you've been warned about aiming heads and saving bullets it really doesn't work that way.

In the end, the problem is the helicopter. Once it shows up and drops the package, they start shooting at you hard, and you shoot back, but I couldn't figure out how to take it down. I tried to hit the artillery guns, I even shot the propeller, but nothing happened. Helicopter just kept shooting until I was dead. In the end I figured out that there are not tricks, the only way to bring the nasty chopper was to keep shooting and shooting until it explodes. So if it takes more than you would expect as 'normal' don't worry. Beside that, game is pretty cool. I liked 3d character modeling and the street are also done in 3d, which is nice. Game is smooth and flawless and I really liked smooth transitions between the levels, so I really don't see the lack of details much of a problem. You'll enjoy this one I promise!
