Super Sonic Doom

Super Sonic DOOM is a megawad created by the Ultimate DooMer. The overall look and feel of DOOM is still there, but elements from Sonic the Hedgehog games are added, such as springs, monitors, and even special stages.

You play the role of a marine named Damage, that receives the mission to stop a sinister madman named Firestarter, and seven other marines known as the Seven Deadly Sinners. Before Damage could even reach the intended location inside a stolen FAC shuttle, it gets shot down by an anti-aircraft gun, forcing Damage to make an emergency escape, and ends up arriving at Sunset Island. He must make his way through the dangers set up by the Seven Deadly sinners and Firestarter, or die trying.
