Origin Defense Idle is a progression-driven tower defense game where a lone stronghold stands against endless waves of geometric enemies.
Survive increasingly dangerous attacks, destroy bosses, earn resources, and turn every battle into lasting progress. Build your tower your way, unlock new systems, and push further through increasingly difficult tiers.
BUILD YOUR DEFENSE
Upgrade your tower during battle and strengthen it permanently between runs. Invest your resources into multiple progression systems, including the Workshop, Skill Tree, Laboratory, and Cards, to shape your build and increase your power.
SURVIVE THE SWARM
Enemy waves grow stronger as you progress. Adapt your upgrades, improve your damage and survivability, and prepare for powerful bosses that will test how far your build can go.

PUSH THROUGH THE TIERS
Each new tier raises the stakes with stronger enemies, tougher bosses, and greater rewards. Improve your build, unlock new opportunities for progression, and see how far your defense can survive.
PLAY YOUR WAY
Origin Defense Idle combines active tower defense with long-term incremental progression. Optimize every upgrade, chase achievements and higher tiers, or build a powerful defense and let your progress grow over time.
