Fail in Ultimate Zombie Defense due to empty armor?

In the intense battles of Ultimate Zombie Defense, nothing is more frustrating than seeing your armor deplete right when you are on the verge of repelling a zombie horde. This sudden vulnerability often leads to game over, wasting hours of progress. The Refill Armor modifier is designed to eliminate this core frustration. It frees you from the constraints of scarce resource drops or long cooldowns, giving you the power to restore your defensive status at will. By activating this feature, your character gains near-infinite durability, allowing you to calmly face every increasingly difficult wave of zombies. You are no longer passively scavenging for supply crates but actively controlling the pace of battle. This means not just higher survival rates, but the freedom to experiment with aggressive tactics and experience pure combat joy. Say goodbye to unexpected deaths caused by broken gear. Enjoy the sense of achievement and freedom that comes with strategic defense, making every sortie confident and powerful.
