SALVO SPIRE is a sci-fi tower defense game that combines vertical construction with 360-degree defense. Start with a single weapon floor and build your own towering arsenal to face enemies approaching from every direction. Different floor combinations and construction orders create distinct defensive builds.
Build upward. Find your defensive style.
What you place on each floor—and what you build first or later—changes how your tower fights. Combine weapon towers with different roles and arrange their layers to balance damage, crowd control, and defensive stability. Experiment with construction order to get different results from the same arsenal.
Diverse weapons, working together
Combine weapons and support towers with distinct roles. Suppress enemy groups with sustained fire, concentrate damage on threats, or buy time with slowing, freezing, and knockback effects. Make your floors work together to create a firepower system that suits your playstyle.
Watch every angle. Direct focused fire.
Enemies close in from all sides, and any direction can become the focus of your defense. Rotate your view around the tower, redirect concentrated fire, and deal with threats approaching its base. Your decisions during combat matter just as much as your construction choices.
Expand floor by floor. Keep upgrading.
Between battles, choose your next step: add a new floor to cover a weakness in your build, or upgrade existing weapons to strengthen its core firepower. Balance expansion and upgrades as the assaults grow more intense.
Lose the bottom floor, not the fight
Enemies target the base of your tower. When the bottom floor is destroyed, the floors above fall and form a new defensive line, changing the original layout. As long as your tower still stands, you have a chance to redirect your firepower and fight back.
Survival challenges and endless assaults
Progress through Survival mode and experiment with different construction strategies. In Endless mode, face increasingly powerful assaults and discover how long your defensive build can hold.
