Orbit Squad: Idle Siege RPG

Command a band of mercenaries as they charge toward fortresses, pulled in by their gravity!

Orbital Mercenaries is a physics-based idle siege game where your soldiers orbit around fortresses, smashing into walls and battling enemies. Combat plays out automatically, but choosing which classes and heroes to deploy—and when to unleash tactical magic—is entirely up to you.

[Physics-Driven Siege Battles]

Mercenaries crash into fortress walls, bounce away, and charge back toward their targets. Soldiers, enemies, and projectiles collide and scatter across the battlefield, creating a different combat scene every time.

[A Variety of Unique Classes]

Collect and upgrade Infantry, Swordsmen, Chargers, Heavy Knights, Archers, Mages, Armored Axemen, and Priests. Each class has its own combat style and role, including rapid charges, chain attacks, wall breaking, long-range sniping, and healing allies.

[Build Your Own Mercenary Squad]

Deploy your preferred classes into a limited number of slots and create a formation suited to each battle. Level up your mercenary squad to unlock additional deployment slots and new progression features. Promote and evolve your classes, choose special abilities, and develop a strategy of your own.

[Diverse Campaigns]

Conquer the Orc Thorn Fortress, the Legion of the Dead, the Demon Horde, and the Human Empire. Each region introduces different fortress walls, environmental effects, enemy types, and unique abilities that require new strategies.

[Powerful Heroes and Tactical Magic]

Advance through the campaign to unlock special heroes and send them into battle. Upgrade and evolve your heroes to gain new abilities. When the battle turns against you, unleash tactical magic to turn the tide.

[An Ever-Growing Siege Force]

Use rewards earned from each stage to strengthen your soldiers, magic, regional abilities, and mercenary squad. Challenge tougher walls and more powerful gatekeepers as you push for a new highest-stage record.

Build your mercenary squad now and bring down every fortress standing at the end of the orbit!
