Sonic the Hackable - Splash Hill Demo

By CHRdutch


Sonic the Hackable is a Sonic 4/Dimps styled Sonic ROM hack of the original Sonic the Hedgehog for the Mega Drive. It features new layouts, new zones, new moves and a remixed soundtrack by LackofTrack and others.

Story

After Dr. Eggman's defeat in Sonic the Hedgehog 4: Episode II, the Death Egg MK II is left without a power source. Sonic, whose escape pod has landed back onto Mirage Island, is left without Tails, who seems to have landed somewhere else. Knowing Dr. Eggman's resilience, Sonic knows that the evil doctor will stop at nothing to find a new power source to breathe new life into his wicked contraption. With this in mind, Sonic storms off towards the Mad Gear, Eggman's power plant that was powerful enough to refurbish Metal Sonic. Eggman's true plans are unknown, but breaking into his base and destoying his only known source of power sounds like a good start to stop whatever it is.

Now, Sonic must travel through Mirage Island one final time to put an end to this saga once for all.
