BigTree TopGun is a top-down shooter that employs the familiar "rotating turret" mechanic; enemy bugs enter the playing field from all angles, while each level the amount of enemy waves increases. The onslaught consists of a diverse array of evil little buggers that fly in erratic, difficult-to-hit patterns and possess innate abilities that make them immune to certain types of attack.
