Gunner: Free Space Defender is the first person 3D space shooter.
Good old motto "Kill '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 protect friendly objects and destroy all attacking enemies. 12 types of Primary weapons and 6 types of Secondary weapons will help you to do the job. Bullets for Primary weapons are unlimited, but each one will cost you a score point. Secondary weapons are limited in ammo.
There are two game play modes: Campaign and Survival; each with 32 levels will not leave you indifferent and will not let you get bored.
This game also available for Android Devices by Google Play.
