About Protodroid Delta
Protodroid Delta is a 3D action-platformer set in Radia, a solarpunk vision of Earth’s future. You play as DeLTA, an advanced android created by the roboticist Dr. Shelton to show a skeptical world what AI can become. When the Vyper gang attacks Shelton’s lab, he equips DeLTA with combat subroutines and weapons for self-defense. After she repels the attackers, DeLTA sets out to defend the region from the growing Vyper threat and earn the city’s trust.
Explore Radia
Radia is a hopeful but non-utopian future where solar power is the dominant energy source and humanity, technology and nature coexist. As you travel through its stages, you meet a varied cast of characters, including Vyper Masters, rival roboticists and fellow Protodroids who follow a different code.
Fight the Vypers
DeLTA uses her dexterity and distinctive arsenal to jump and shoot through challenging 3D stages. The gameplay is designed to capture the fast, fluid feel of 2D classics. You can take on the stages in any order, face personality-filled bosses on their home turf and claim their unique weapons.
Find upgrades
Search the stages for upgrades and power-ups that enhance DeLTA’s capabilities. You can also locate the fellow Protodroid AnnDROID in each stage to master new blade techniques.
