Gunner: Galaxy Defender 3D is a first-person 3D space shooter game available on the iPhone. The game's main objective is to protect friendly objects and destroy all attacking enemies. As the gunner, you control a space turret and have access to 12 types of Primary weapons and 6 types of Secondary weapons to complete your mission.

Primary weapons have unlimited bullets, but each shot will cost you a score point. On the other hand, Secondary weapons have limited ammo. Be careful though, as the primary weapon can overheat during intensive firing, leading to misfires. Keep an eye on the temperature gauge located under the ammo counter.

The game offers two gameplay modes: Campaign and Survival. Both modes consist of 32 levels, ensuring an engaging and challenging experience for players. Additionally, Gunner: Galaxy Defender 3D features Game Center integration, allowing players to earn achievements and compete with friends on the leaderboard.

With iCloud support, players can back up their save game, achievements, and leaderboard scores, and even continue their game on multiple devices. Gunner: Galaxy Defender 3D offers an immersive space shooting experience with a variety of weapons and challenging gameplay modes.
