Salvo Spire

A tower defense game

Salvo Spire is a sci-fi tower defense game for PC, built around a tower you construct floor by floor. You start with one weapon floor and defend against enemies approaching from every direction. Your tower’s layout matters: the floors you choose and the order you build them affect how its defenses work.

Building a defense

You combine weapon towers and support towers with different roles. Sustained fire can suppress groups, concentrated fire can focus on threats, and slowing, freezing, or knockback effects can give you time to deal with an attack. Arranging these towers across your floors lets you balance damage, crowd control, and the tower’s defensive stability.
