About Mayday Protocol
Mayday Protocol is an asymmetric co-op puzzle game about communicating to keep a failing aircraft in the air. One player is the Pilot, who works through cockpit puzzles without knowing how to solve them; the other players are Co-Pilots, who consult a manual of rules and solutions but cannot see the cockpit. The Pilot describes what is on screen, and the Co-Pilots guide them through the answers.
Work together
The Pilot faces real flight instruments, including gauges, warning lights and screens displaying puzzles. The screens contain locked systems, controls that require input and visual clues to interpret; each puzzle corresponds to a solution in the Co-Pilots’ manual. The Co-Pilots must use the Pilot’s descriptions to identify the right instructions. Voice communication is the team’s only tool.
Beat the clock
Each level presents a sequence of puzzles to solve before time runs out. The challenges include color sequences, frequency tuning, grids and shape-based systems. Too many mistakes or running out of time causes the plane to crash, so the players must communicate and solve the puzzles under pressure.
