7. ZF-1 Assault Weapon - The Fifth Element

The Swiss Army Knife of assault rifles. The ZF has rockets, darts, tracer bullets, netting, a flame-thrower, freezing gas-anything and everything you need to destroy the universe. The only problem is, a crate of these bad boys will set you back four ancient, mystical stones each. We don't care if you're the Sultan of Dubai, that's some serious scratch.
