List of unofficial Sonic the Hedgehog media explained

Unlicensed developers and fans have created unofficial Sonic media, especially video games, relating to the Sonic the Hedgehog franchise. These products include video games, video game mods, ROM hacks, comics, and animations. Due to the popularity of the franchise, some of these products have received media attention. Sega is permissive of most fangames, as long as they are not for profit.^[1] Some Sonic fan game developers have gone on to work on official Sonic content, most prominently Sonic Mania (2017), while others have subsequently created original games that feature Sonic-inspired mechanics.

Video games

Fangames

The following are all original games based on the Sonic series:

• Green Hill Paradise Act 2 is a 3D Sonic game built by Daniel "SuperSonic68" Coyle and other collaborators with the 3D Sonic Games Development Kit. This game gained notability for receiving a positive response from Sega.^{[2] [3]}
• Sonic Utopia is 3D Sonic game demo, which demonstrates 3D Sonic gameplay in a large open world.^[4]
• Sonic Before the Sequel is a 2D Sonic game set in between the events of Sonic the Hedgehog and Sonic the Hedgehog 2. The game's original release in 2011 had a soundtrack with reused music coming from different video game franchises like Kirby, but a second release in 2013 came with original music specifically for the game. The game received wide critical praise for its faithfulness to earlier titles. Two sequels, Sonic After the Sequel and Sonic Chrono Adventure, were later developed and released in 2013,^[5] the latter incorporating Metroidvania and time travel elements. The creator would later develop an original platform series with Sonic-inspired mechanics, Spark the Electric Jester.
• Sonic Dreams Collection is a parody game presented as a Dreamcast development kit containing cancelled Sonic games. The game caught media attention for its bizarre nature and its intent to lampoon the Sonic fandom.^[6]
• Sonic Fan Remix is a 2.5D Sonic game created in Unity that features reimagined levels from past Sonic games.^[7]
• Retro Sonic is a 2D Sonic game created by Christian Whitehead. It is the first game to use the Retro Engine (the engine used for the 2011 remaster of Sonic CD), and later merged with two other Sonic fangames, Sonic Nexus and Sonic XG, to form Retro Sonic Nexus, a collaboration project made by Christian Whitehead.^[8] Retro Sonic Nexus was ultimately cancelled in 2011, splitting up the three projects, while Christian went on to work with Sega to make the 2011 remaster of Sonic CD.
• Sonic Robo Blast 2 is a 3D Sonic game that uses a modified version of the Doom Legacy engine and has been in development since 1998. The game gained notability for being the first 3D Sonic fangame, and it continues to be updated by its developers and supported by its community to the present day.^[9] A kart racing variant, Sonic Robo Blast 2 Kart, was released in November 2018 using the same engine;^[10] a sequel, Dr. Robotnik's Ring Racers, was released in 2024.^{[11] [12] [13]}
• Chao Resort Island is a fangame for Microsoft Windows and macOS, based upon the Chao-raising minigames in Sonic Adventure.^[14]
• Sonic World is a game heavily based upon the Sonic Adventure titles and Sonic Heroes. It features over 30 playable characters and the ability to make Heroes-style teams, as well as remastered levels from various Sonic games.^[15] An upgraded version called Sonic World DX received its first demo release in 2020, and remains in active development.^[16]
• Sonic Z-treme is a homebrew Sega Saturn game that aims to recreate concepts from the canceled game Sonic X-treme using original code. It can be made to run on real Saturn hardware if it is burned to a disc.
• Sonic the Hedgehog 2 HD is a high-definition fan remaster of Sonic the Hedgehog 2 in development. The final version is planned to feature additional stages and the ability to play levels as Knuckles the Echidna.^[17] Some previous members of the development team would go on to work on Sonic Mania.^[18]
• Sonic Eclipse Online was a 3D Sonic game on the game creation platform Roblox. After the developer Arnold "DoctorRofatnik" Castillo had his account banned for accusations of sexually preying on a child, he transferred the game to a friend's account and continued profiting from it. Roblox refused to take the game down as they did not view it as a safety concern. Later, after being notified, Sega had the game taken down via a copyright infringement notice. (Castillo was later sentenced to 15 years in prison for transporting another child across interstate lines for sex.) The case was used by People Make Games and Bloomberg Businessweek to accuse Roblox of practices compromising child safety.^{[19] [20]}
• Sonic Omens is an episodic 3D Sonic game that garnered controversy regarding its funding through Patreon. Discourse surrounding the project led Sonic social media manager Katie Chrzanowski to clarify via Twitter that "So long as no profit is involved, there is usually no issue with y'all using our blue boy to hone your art and dev skills – but, for legal reasons, I can't promise all content is OK".^{[21] [22]}
• Sonic GT is a finished 3D Sonic game built on the fan-made Bumper Engine. It iterates on gameplay elements from the series' official 3D entries.^[23] The creator would later refine many of the game's mechanics for an original project, Rollin' Rascal, which was crowdfunded via Kickstarter in 2024.^[24]
• Sonic 3D in 2D is a reimagining of Sonic 3D Blast as a classic-style 2D Sonic game. Unlike the original, Tails and Knuckles are included as playable characters and retain their abilities from the classic titles.^[25]

The player takes control of Sonic from a first-person perspective and must pump their arms in the air to accelerate forward. Additional speed can be acquired by taking advantage of the game's level terrain. It debuted at the 2020 Sonic Amateur Games Expo and supports SteamVR-compatible headsets.^[26]
• Sonic and the Fallen Star is a 2D Sonic game featuring original levels and music. It is inspired by multiple 2D Sonic titles, Sonic Heroes, and the Before the Sequel and After the Sequel fangames.^[27]
