Excellently made game, good graphics, excellent sound, great AI, great physics, and an overall amazing sniper simulation
The sound of the weapons was extremely well done. It was accurate according to the enviroment and really immersed me in the game. Beyond that the music was extremely suspenseful and well done, the background noises sounded very realistic, and the talk of the enemies in their native languages was excellent.
The AI was also extremely well done. It is one of the only games I have ever played where I have been flanked by an AI opponent and killed from behind, very well done.
The physics of the bullet and the effect of following the bullet are also fantastic. The following of the bullet drives you to get "Long Range Headshot"s just to watch the bullet fly through the air and hit the enemy in the head in slow motion.
The stealth aspect, weapon accuracy, realism, movement of your character, and simulation of the sniping enviroment is very well done.
The only complaints I have is the lack of Cooperative multiplayer, the lack of sniping from high elevation, and the weak storyline. But these flaws can be overlooked to see what a fabulous game it is.
