Dr. Robotnik's Ring Racers is a kart racing video game originally based on the 3D Sonic the Hedgehog fan-game "Sonic Robo Blast 2", which itself is based on a modified version of Doom Legacy. It is the sequel to Sonic Robo Blast 2 Kart. Hang up your sneakers, because Dr. Robotnik and his ex-enemies are going go-karting! Use the untapped potential of rings to super-charge your vehicle across more than 200 crazy courses. With over 20 unique items and some of the hottest moves on this side of the Floating Island, this is Racing at the Next Level!

SRB2Kart is a classic styled kart racer, complete with beautiful courses, and wacky items. Of course, because it’s SRB2Kart, it has a Sonic twist that really shows the classic charm that a lot of us know and love from the good old days. We have 100 jam-packed maps for you to bump, explode, and sparkle your way through, from luscious beaches, to Eggman’s dance floor, to England on a good day. All lovingly crafted by many different people. You’ll notice almost every aspect of the game has an immense love and inspiration from the classic sonic games. From the items such as Ballhog, which literally throws bouncey explodey balls at people, to the maps which are bursting with that Sonic feel. Of course, you'll only start off with a few cups available, but you can unlock more by playing offline/online matches. Alternatively, you can immediately jump into challenging yourself and race us personally in Staff Attack mode! Don't worry, we'll go easy on you.

Sonic Robo Blast 2, abbreviated as SRB2, is a fan game for Windows and DOS platforms. It is a 3D platformer developed by a group called Sonic Team Junior, using a modified version of the Doom Legacy source port of Doom, to allow for such things as optional analog control and true room-over-room (something not possible in the standard Doom engine), as well as the standard gameplay elements Sonic games are known for. It has been in the works since 1998 and is currently nearing completion, though several parts of the game are still missing. Sonic Robo Blast 2 is closely inspired by the original 2D Sonic games for the Genesis and attempts to recreate a game with this style in 3D, though it also borrows elements from the current Sonic games, such as Sonic's signature Air Spin Attack. Entirely original to SRB2 is its Multiplayer mode, a variation of classic first-person shooter games with Sonic elements. Due to being built with a modified Doom Legacy engine, the game is also very easily customizable. Custom levels, characters and even source code modifications can be created with the help of external editors.

Features: - Easy to digest physics and moveset taking the best from Sonic Adventure 1 and 2! - Outstanding support for controllers and simple mode. Give it a try on SA-Sonic and be surprised! (NOTE: Bind "Center Camera" to a comfortable button, you might prefer it over manual camera turning!) - A fleshed out super form, custom NiGHTS moveset, many easter eggs, and deep-rooted mechanics hardcore fans will instantly recognize! - A custom Adventure menu for cosmetical and accessibility options! After around a year of work, Adventure Sonic (AKA SA-Sonic!) is complete! SA-Sonic heavily alters the game's physics to resemble Adventure 1 and 2's, whilst scaling everything to still feel good within an SRB2 context. Sonic has more turning control and air resistance like in Adventure, and much stronger interactions with slopes! SRB2 normally encourages you to stay airborne to keep your speed and zoom over obstacles, but SA Sonic is instead at his fastest on the ground! Adventure Sonic supports all control styles! (strafe, standard, & simple) Normally SRB2 prioritizes keyboard+mouse, with controllers being a massive self-induced handicap. But SA-Sonic was designed with a controller-play in mind, as that's what comes to mind for us when we think "3D Sonic platformer". The primary goal was to make Adventure Sonic control naturally for both casual players and SRB2 physics loyalists both. Here's hoping we achieved that goal!
