Zombie Gunship Survival by Flaregames is touted as one of the best mobile zombie killing games of all time, and it justifies this in all means. This game has realistic graphics, night vision simulation in airplanes and drones, extensive weapons, and quick missions that need your strategies to succeed.
The action game is played entirely from air, right from the aviator's seat of AC 130.
While you'll not be engaged in any air-to-air combat, you will be assisting the ground troops to complete their petty missions. Every task would be timed less than three minutes but requires deep concentration to perform and succeed.
The story-line is simple. You and few troop members are the ones surviving in this world where everyone turned into zombies. Since they attack other creatures by nature, you have to stop them from approaching your men and save the leftover humans. You'll be seated in the aviator's seat of AC-130 artillery gunship, which drew its inspiration from the world's largest gunship made by Lockheed Martin.
Your screen is filled with a cockpit dashboard, with all the plane handling tools and weaponry access. All you need to do is keep an eye on the floor. Watch out for any zombie movements towards the base camp and wash them off by shooting from your gunship. Your task is to assist ground troops in completing theirs. Also, you'll be spotting the precious resources like gold and other metals needed for your upgrades.
Capturing them could help strengthen your base camp defenses by building barracks and upgrading tower defenses. At the same time, these can be used for upgrading your weaponry for more powerful shots. Zombies can get sneaky, and numerous at once, thus it needs your utmost concentration on the land to thwart them from approaching your men.
Also, you blow up obstructions to let your troops pass and complete their missions. And if you feel that you're good enough at these things, switch on to play in weekly events against other gunners and showcase your defender skills. You can also play with others in the community and discuss tactics to better yourself in the game.
