Sonic ERaZor is a hack of Sonic the Hedgehog created by Selbi. This hack is unlike many other hacks, featuring a heavy in-game story line, unique challenges, and never seen before gameplay mechanics. These elements are often somehow related to explosions, which is why this hack is sometimes called, "What if Michael Bay directed Sonic 1?" When first released back in early 2010, Selbi stated that this hack has no goal whatsoever and any ideas he came up with just went in. Today's...

Sonic: The One Ring is a hack of the original Sonic the Hedgehog game for the Sega Mega Drive, created by Mercury. Its defining (and titular) feature is that in each Act, all rings but one have been removed, and Sonic cannot complete the Act without this One Ring in his possession. Thus, in each Act, Sonic must search for the One Ring that will afford him the opportunity to progress. Several alterations have been made to the game, to somewhat balance the lack of rings, and allow backtracking...

The idea of this game is that you and another friend of yours select a character (one being Sonic and the other being Tails) and you both battle it out to try to gain as many hits on Eggman. The catch is that Eggman only gets destroyed when the timer runs down to 0 (unless it's a draw at that time, then, it will wait for another hit). The player with the most hits at the end of the timer wins! You can also win if the other player dies before the timer runs out (if respawn mode is off). The...

Super Sonic's abilities from Sonic 3 & Knuckles were added in addition to using the Super Sonic sprites of Sonic the Hedgehog 2.

Sonic 3D: No Flickies is a hack of Sonic 3D: Flickies' Island made by Sik. The game remains mostly unchanged; however, the Flicky collection system (part of the core gameplay of the original game) has been removed, allowing the player to complete the levels without needing to collect all the flickies in the level to advance. This makes it much more similar to traditional Sonic games, where the goal is to simply make it to the end of the level without dying.

Sonic the Hedgehog has been cursed! Now, when he collects rings, his rings counter counts DOWN instead of up! And if he collects a ring when he has a counter of 0, it's lights out. Sonic 1 never seemed so... Intimidating. Made by Campbellsonic.

Dr. Robotnik is an asshole. He stole the sacred Chaos Fries, cooked in Chaos Emerald-infused oils. With them, he has built an army of robots, and his flying fortress, Chrome Castle Zone. If you can acquire the Chaos Emeralds, you may be able to neutralize the Chaos Fries.
