About this game

Defense Core is a high-energy merge defense game set in a bold industrial world where machines roar, factories blaze, and heroes are built for battle. Merge units, upgrade tech, and deploy powerful defenses to hold the line against endless enemy waves. Build your core from simple parts into unstoppable machines, unlock specialized defenders, and strategically combine units to trigger massive power spikes. Every decision matters as enemies grow stronger and the battlefield evolves. With satisfying merges, explosive combat effects, and deep progression systems, Flux: Defense Core blends idle-friendly growth with tactical defense gameplay. Whether you play actively or let your defenses grind while you’re away, your factory never stops fighting.
