Iron Defense

About Iron Defense

Iron Defense challenges you to protect a scrapyard wall by controlling a turret that fires at approaching waves of junk robots. Use the mouse or touch controls to hold and drag elemental abilities like fire, ice, and lightning onto the battlefield, strategically slowing or damaging enemies. Between rounds, invest earnings in upgrades for your turret, wall, and automated defenses to improve your chances against tougher waves. The game features a long campaign of 100 stages with escalating difficulty, followed by an endless mode that tests how long your fully upgraded defenses can hold. Combining action and tower-defense elements, this 2D arcade shooter offers a focused, skill-based experience.

How to Play

Hold the mouse button or your finger on the field to fire at the robots. Drag the fire, ice or lightning button onto the field and release to cast it; release on a button to cancel. Abilities use energy, which refills over time, and the + button refills it for crystals. Win a stage by destroying every wave before the wall falls. Spend gold and crystals in UPGRADES between stages. Clear stage 100 to unlock Endless.
