Why will it not let you change weapons, none of the numbers are switching for me?
You have to have the weapon purchased first.. If you do and it's not working then you probably have older version of Flash Player. Try to upgrade it http://get.adobe.com/flashplayer/
There are no clear instant button controls, there is no music of any good caliber and in all it's just awful. How is this even third in the best 50 flash?!
