CodePhantom Indie Mecha Action Gets Steam Demo Ahead of 2026 Release

Japanese indie developer RRR has released a free demo for CodePhantom, a single-player 3D mecha action game available on Steam. The title features high-speed ground and aerial combat where players pilot the PHANTOM humanoid command mech to complete missions and increase their sync rate.

The gameplay allows for extensive loadout customization, equipping two primary weapons like rifles or gatling guns alongside one secondary option such as a laser sword. Movement relies on boosting, jumping, and stepping, with mechanics shifting between horizontal ground traversal and full three-dimensional aerial maneuvering. Players can use keyboard and mouse or a controller.

Progression centers on the Sync Rate system, which boosts attack power, defense, and speed as enemies are defeated, though taking damage reduces this metric. The full game will include over twenty missions and is scheduled for release in 2026.
