I had a lot of fun playing this but thought that some of the guns were beyond arbitrary and unnecessary to the game. Why do I want the sniper rifle when it can't do anything? Half of the screen gets filled with projectiles and congratulations you can't shoot the things behind them because you are too busy shooting things out of the air. Seems a little silly. I ran into the same problem with the Rocket Launcher and had to switch back to my Uzi to get anything done. Other than some minor balance issues this game is a lot of fun and I enjoyed playing it.
