Acidic Rain Alien Prototype

Inspired by a Praying Mantis - the scope uses four small round cameras (2 on each side) to seek out its target, a floating scope??... nonsense. The scope is being held up by a strong magnet right under the belly, on top of the gun. Wherever the gun goes.. the Scope goes.

The ammo is Acidic Liquid being held at the back of the gun, under the stock, almost like a pouch. The weapon will shoot a strong acidic beam able of melting anything in its path.

This is.. Acidic Rain.
