About this game
Iron Defense places a turret on a scrap wall while waves of junk robots approach from the right. You control the firing and add fire, ice or lightning abilities to protect the position. Salvaged gold and crystals improve the turret, wall, electrified floor and supporting gun pylons between stages. The campaign leads through escalating waves and bosses, with Endless mode available after its final stage.
How to play
Hold the mouse button or a finger on the battlefield to fire at incoming robots. To use an ability, drag its button onto the field and release; releasing over a button cancels the cast. Abilities consume energy that replenishes over time, so decide when a wave needs extra help. The plus button spends crystals to refill energy. Defeat every wave before the wall collapses, then visit UPGRADES to strengthen the parts of the defense that struggled. Clearing stage 100 opens the Endless challenge.
