a.defender is a turret defense game where you can upgrade your stats not only while in game but also out of the game as permanent upgrades for your next play-through!

Have up to 25 turrets defending at a time. Don't let the enemies pass your lines of defense and don't run out of turrets!!

Upgrade your turrets' default stats, amplify your turrets with turret boosters and badges, and unlock permanent perks including auto turret mode, start @ wave 1000, as well as double ABP & ABG drops!

Can you unlock Tier 2? 3? How far can you go?
