Iron Defense

Iron Defense is a one-screen defense shooter set in an industrial scrapyard. Hold a turret on a scrap wall while waves of junk robots march in from the right. Hold to fire, and drag fire, ice and lightning abilities onto the field. Between stages, spend salvaged gold and crystals on your turret, the wall, an electrified floor and auto-gun pylons. Fight through a 100-stage campaign with bosses, then climb the endless stages to see how far a fully upgraded defense can hold.
