i have a good one.
A Fractal De-nebulizer.
it uses 3 sapphires to focus artificial light energy into a charging capsule.
It then fires a cloud of metal shavings through the heated charging capsule to form a thick ball of molten steel which sticks to organic surfaces ((such as the facial area)), but is hot enough to melt/fuse with most metals or nano-weave materials.
It weighs roughly 6.7 pounds, and can use whatever scrap metal you have laying around as ammo. (( it basically crushes the steel and shaves it until the reserve container is full.)) The container which holds the metal shavings can hold enough ammo for 56 shots, and cant be removed, and replaced for faster reloading, or so you can store ammo ahead of time for later use.
Because the shavings are in the controlled enviroment of the reserve capsule, they never rust or solidify unless the reserve capsule itself it cracked, broken, or damaged beyond repair. ((the container itself is made of a nano-weaved carbon mesh wish forms to fit the ammount of metal shavings inside of it, and is harder to damage because of its flexability))
All in all its an effective weapon against enemy infantry, living or otherwise, and can be used in almost any situation. Using even the spent cartriges for tradition firearms as ammunitions.
Thus, when your allys use ammuntition, you gain ammuntion.
Whoa, that was alot more typing then i thought it would be.
