The battle for the Empyrean Realm has begun. A ruthless enemy commander has launched a full scale invasion, searching for the Empyreal Core, an ancient secret technology hidden deep within the realm. As the last line of defense, you must deploy, upgrade, and adapt a wide array of military, economic, and support sites to survive increasingly intense enemy assaults.
Empyrean Defense is fast paced, challenging, and deeply strategic. Success depends on quick decision making, smart positioning, and long term planning as enemy pressure escalates.
Play your way. Empyrean Defense features full mouse & keyboard and controller support, including a great experience on Steam Deck.
Command a variety of defensive and support structures, from sniper towers and missile launchers to research centers and power plants. Each site plays a vital role in your defense:
Military: Engage enemies directly with a mix of classic and advanced structures
Economic: Generate valuable resources to fund expansion and upgrades
Power: Maintain an energy grid to support advanced infrastructure
Support: Research new technologies that enhance and specialize your defenses
Customizable Sites: Upgrade and modify key components to adapt to any battlefield
Diverse Enemy Waves: Face ground, naval, and airborne units, including powerful bosses
Player Abilities: Call in airstrikes, deploy protective bubble shields, and even manipulate the battlefield with lightning storms and blizzards
With 40+ skills across 4 branches in the skill tree, 20+ enemy units and bosses, 25+ sites to build and upgrade, and 15+ active abilities to learn, every decision matters and no two defenses play the same.
Defend forests, deserts, snowy mountains, and warn torn cities across 27 regions. Each region introduces new threats, terrain challenges, and enemy tactics that demand constant adaptation.
Follow a progressing campaign featuring four core characters who provide tactical guidance and battlefield banter as the conflict unfolds. This war is about more than survival. It is about stopping the enemy commander before he unlocks the power of the Empyreal Core.
Can you keep up, adapt under pressure, and prevent the realm’s secrets from falling into enemy hands?
