Relay Protocol is a logic-based puzzle game built around experimentation, spatial reasoning, and energy-based mechanics. Play solo or with another player inside a mysterious industrial facility, using energy beams, reflective surfaces, logic devices, and environmental mechanisms to solve interconnected test chambers. Each player has a distinct role, and success depends on understanding how your actions affect your partner’s side of the puzzle. Redirect lasers, activate surfaces, manipulate geometric signals, and coordinate timing-based interactions to progress deeper into the facility. Every room is built around clear rules, but the solutions require observation, experimentation, and teamwork. Relay Protocol is designed for players who enjoy clean puzzle design, minimalistic sci-fi environments, and cooperative challenges where both players matter. Features Full campaign playable solo or in two-player co-op Logic-based puzzle chambers built around experimentation and spatial reasoning Energy beam mechanics with reflection, redirection, and signal transformation Specialized units with distinct functions Reactive surfaces, logic devices, and interconnected environmental mechanisms Minimalistic industrial sci-fi atmosphere Designed for players who enjoy clean puzzle design, discovery, and systemic problem solving
