Sonic: Project Survival is a Sonic fan game that is Mega Drive-style Sonic platformer, with original zones based of classic games in the series.

When a mysterious island seemingly appears from nowhere, Dr. “Eggman” Robotnik’s mischief leads him to launch an investigation on this secluded island. His findings reveal a lost civilization, gone corrupt from the power of super animals that inhabited the island. The doctor organizes his newest plan, to use these animals to power Superpowered Badniks, and begins building his base on the island. After the doctor falls under attack from the supercharged animals, he seeks refuge on an artificial island constructed nearby. Now, its up to Sonic and his friends to put a stop to the doctor’s plans, and save the mystical creatures from doom.
