Show the world the potential of AI in Protodroid DeLTA, a fast and fluid 3D action-platformer set in a beautiful and hopeful solarpunk world, featuring a colorful cast of characters to meet and bosses to defeat.
Welcome to Radia
In a vibrant vision of Earth’s future, the world-renowned roboticist Dr. Shelton has created one of the first Protodroids, a hyper-advanced android named DeLTA with near-human levels of intelligence. DeLTA was made to be the change that shows the world the promise of what AI can become—and so she sets out to prove to a skeptical world she's more than “just a robot.”
However, when a gang of Vypers attacks Shelton's lab, the doctor is forced to enable DeLTA’s combat subroutines and retrofit her with weapons systems for self-defense. After DeLTA successfully fends off the attackers, Dr. Shelton sets DeLTA on a new course: defend the region against the rising Vyper threat, earn the city’s trust and affection, and show the world the true promise of what AI can become.
