Needs work.
Ok, last time I trashed someone in a review, I was just an insultinbg twerp. This time, I'm gonna try and be a bit more constructive.
First: There aren't that many controls, just list them at the begining. The first time through, I didn't bother reading the instructions, so after I killed everyone, I didn't know how to end the level.
Second: Techno and Terrorism go together in the sense that they're both great evils of our time, but the music really just didn't fit the game.
Third: Some kind of "fade out" needs to be shown on the screen not seen through the scope. Either apply a "blur" effect or a zoom out, like in "Scope Assault" http://www.newgrounds.com/portal/view.php?id=29805
