Eco Shooter: Plant 530

This is a first-person shooter in which players use a "Recycle Canon" to blast at alien creatures made out of tin cans. Players control a human character named Mac, who is on a mission to stop the alien "Cannoids" from destroying Earth. If players are attacked by the alien cans, their screen flashes red and a grunting sound can be heard. The constant cannon fire can cause aliens to explode in a burst of light as their can limbs, torsos, and heads fall apart.
