THE MURDER OF SONIC THE HEDGEHOG | FULL GAMEPLAY

To celebrate Amy Rose's birthday, she and her friends Sonic, Tails, Knuckles, Espio, Vector, Rouge, Blaze, and Shadow gather in the Mirage Express, a train designed for special events, to participate in a murder mystery game. The player controls a new quokka employee aboard the train, who is directed by the conductor to assist the participants as needed. Shortly after the game is meant to begin, the train speeds up suddenly and causes the player, Amy, and Tails to be thrown back into a storage room and knocked out.

When they reawaken, Amy, Tails, and the player return to the dining car to find Sonic, seemingly actually deceased. While Amy begins investigating on her own, the player accompanies Tails as they move between the different themed cars, interrogating each of the participants to verify their alibis. Progressing through a saloon, a library, a casino, and a lounge, Tails and the player reach the conductor car at the front of the train.

Using evidence they gathered along the way, Tails and the player determine that Espio was the villain of the murder mystery game, and knocked Sonic out with a blowdart. Unbeknownst to Espio, he had been following instructions given by the train itself, which is revealed to have been converted into a giant badnik by Doctor Eggman. Upset with the conductor for planning to retire and leave it behind, the train plots to deliver everyone to Eggman's base in exchange for a bounty, which it intends to use to force the conductor to stay with it forever.

Everyone is dragged back to their cars and locked inside. With the player's help, Sonic, who has recovered, spindashes through the doors to free everyone and reach the conductor car. Racing alongside the train, Sonic and the others attack it until the Flicky powering it is freed, and Espio retrieves it as Amy destroys the train. Before the train deactivates, the conductor promises to never forget his memories with it.

The group disembark at a station, with the conductor reuniting with his wife and beginning his retirement, now accompanied by the Flicky. Sonic buys a cake from a nearby bakery, and everyone wishes Amy a happy birthday. At his base, Eggman is left to lament his plan's failure.
