Great game but I agree it needs to be longer ( I didn't even get all the guns ) I like the physics of the game. A larger arsenal of weapons and possible weapon customization would be cool. I also like to have more of a feel-able difference between the guns ( such as clips sizes, more accurate target finding, or better scopes) the scopes of the better guns could have simple distance zoom and the best have a instant adjustment tool to help get better head-shots. I give five still because it's still a great game.
