Good but could use improvements.

Things I would like to see added:
-The huntsman knife in its own case (and you can only get it in its case and you cant get any other knife in that case)
-The butterfly knife in its own case (and you can only get it in its case and you cant get any other knife in that case)
-Weapon conditions
-Make the knife symbol exceedingly rare item so you cant see the knife before you get it
-Add sound to the app
-Add a price to the weapons so you can see it either while the case is being opened or in the inventory (or both)

Bugs:
-When you open the app it gives you 10 free nova rangers
