Gunner : Free Space Defender ANDROID Game

Good old motto "Shoot 'em all" is probably the best way to precisely describe the game's purpose.
You are the gunner controlling a space turret and your objective is to shoot, shoot and shoot some more to protect friendly objects and destroy all attacking enemies. As a Gunner you have 12 types of Primary weapons and 6 types of Secondary weapons for your space turret that will help you to do the job.
Bullets for Primary weapons are unlimited, but each shot will cost you a score point.
Secondary weapons are limited in ammo, so shoot it sanely.
During intensive firing the primary weapon might overheat and misfire; the temperature gauge that indicates overheating is located under the ammo counter.

There are two game play modes: Gunner Campaign and Gunner Survival; each with 32 levels will not leave you indifferent and will not let you get bored in this shooting game.
