Győr

Eleven months ago an agent vanished in Győr. Their last transmission lasted four seconds and contained a single word: "rooster". The Sierra Program closed the file — now they have sent you to walk the same route. What they did not tell you: not so you would find them. But so they could learn how far you get. Our agent, however, counted on you. In Győr's old town they built a second, hidden trail — in stones, flags, glass eyes, cannons — and at the end the evidence waits that could bring down the entire Program. You just have to get there before the one who sent you. Your past has been erased. Your codename: Sierra 7. The countdown has begun.

Deep on Radó Island, a centuries-old clockwork, the Wave Breaker, has awakened. Its massive brass gears are already turning: when they reach the dead point, hidden sluice gates will open and downtown Győr will be swallowed by the river within minutes. The machine's creators, the secret society of the River Wardens, foresaw the danger. They split the emergency shutdown code into pieces and encoded it into the city's buildings, stone figures and hidden corners. Your task is to reassemble the legendary Machine Book. Watch every detail, because the masters will test your knowledge at the end. Time is running out, the water level is rising unstoppably. The fate of the city is in your hands.
