In Scrap Zone: Idle Defense, you command a defense tower built from salvaged metal and forgotten tech, deep within a hostile scrapyard wasteland. Enemies surge from all directions, growing stronger with each wave. Your tower fires automatically, acting as the last barrier against the swarm. After every successful defense, choose from random buffs to upgrade your setup and forge a unique survival strategy. Use support tools like bombs to obliterate enemies or ice to freeze advancing threats. How long can your scrap-built stronghold withstand the chaos?
