Badspot should add an ammo system that's "hard coded" and will work with all add-on guns and stuff. Basically it'd just be a few lines of code that you would change to tell the game how much ammo you want one mag from your gun to have and then what type of ammo, and then you can spawn magazine items and ammo crates. I also think he make a new HUD and add a health bar and maybe an armour system.
