Solidus

Solidus is a mobile RPG set in the stratosphere, where humanity has retreated to survive a toxic world below. Players command a team of warriors in tactical battles against mysterious entities, combining anime-inspired visuals with strategic gameplay. The game features a rich progression system with unlockable characters, gear, and abilities.

After a cataclysmic event renders Earth uninhabitable, humanity escapes to floating cities in the sky known as Havens. You play as the newly awakened director of one such Haven, tasked with defending it from threats beyond the Cobalt Aegis — a toxic cloud barrier surrounding the stars. As you rebuild civilization, uncover ancient secrets, and lead your agents into battle, the fate of humanity rests in your hands.
