V1 Barrier

The V1 known as "barrier" is a very early game blimp, showing up at only wave 11! It has 20 health, it also has metal panels on the left and right side of it with 1 AD (hits from the front and back will deal direct damage), it also has a  very basic weapon that does 1 damage with a very slow ROF. This can be a threat early in the game, however it's still an easy thing to beat.
