How AI is used
The key art, store capsules and library artwork were created with an AI image generator and edited by the developer. The trailer music was generated with Suno under a paid plan. No AI-generated content is included in the game itself, and the game runs no AI generation and requires no AI service.
The developer's own words, from Steam.
About Superpower Sandbox
No forced story. Just powers.
Superpower Sandbox drops you into an open city with a full set of superpowers and no mission list to endure. Fly above the rooftops, climb through the clouds, dive into the sea, and decide for yourself what happens next.
Charge up, then let it out
Build up your Qi and watch your aura grow. Fire energy spheres and sustained beams, release shockwaves, and switch between kung fu combos and ranged powers. Stop incoming bullets in mid-air and send them back to the shooter.
Physics you can play with
Grab civilians, enemies and objects with telekinesis. Enemies react physically to every hit. Damage buildings until their supports give way and they come down.
A city that fights back
Civilians flee, armed enemies take cover and shoot, and stronger creatures push you harder. Survive waves in horde mode, or just explore at your own pace.
Built with mods in mind
The game is being designed so that powers, characters, enemies, missions and maps can be added as content packs. Public tools for modders are planned; they are not available yet.
An indie project in active development
Superpower Sandbox is made by a solo developer and is still growing. Expect rough edges: follow development and share feedback on the official website.
