In Defense Io, you're in the hot seat of a tank, fighting off increasingly stronger waves of enemies in a top-down survival game.
Blast your way through foes to gather resources, then use them to beef up your tank between battles. The pressure keeps ramping up, so stay sharp!
Choose from over 20 different guns, like homing rockets, spinning blades, and a vortex cannon that catches enemy bullets. Select from eight unique hull types, such as a berserker that packs a punch when your HP is low, a shield for frontal protection, or a kamikaze designed for ramming.
But it's not just about your tank—set up turrets, walls, and gates around your base, upgrade them during the heat of battle, and construct drone hangars that automatically collect resources or repair damage.
Rare cores dropped by tough enemies and bosses are yours to keep forever. Spend them in a permanent meta-shop to unlock new guns, hulls, and buildings for good.
How long can you hold out?
How to play
Use WASD to move around and the mouse to aim and fire.
You can access the shop during combat, not only between waves. Use this opportunity to enhance your stats, purchase new weapons and hulls, and construct turrets, walls, and gates to fortify your base. Defeat enemies to earn resources and immediately invest them in upgrades. Hold out as long as possible — your adversaries will become more powerful with each wave.
