Gunner: 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. 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: Campaign and Survival; each with 32 levels will not leave you indifferent and will not let you get bored. GAME FEATURES: • Game Center Enabled • Earn GameCenter Achievement points and compare your Leaderboard scores with your friends! • iCloud Support • With iCloud enabled, you can back up your save game and all your Achievements and Leaderboard scores, and even continue your game on multiple devices!
