About Knuckles' Chaotix

A mysterious island rose from the sea shortly after the events of Sonic & Knuckles. Dr. Robotnik discovered the island, and found a mysterious ring inscribed with descriptions of the Chaos Rings, ancient Rings infused with Chaos Emerald energy. In order to find these Rings, Robotnik built his base, the Newtrogic High Zone, on the island. Mighty the Armadillo, Espio the Chameleon, Vector the Crocodile, and Charmy Bee also arrived at the island, and ended up being captured by Robotnik and Metal Sonic, and placed in Robotnik's Combi Catcher machine. Knuckles, curious about the strange island, goes there as well, and manages to rescue Espio. The two then go on to stop Robotnik from getting the Chaos Rings.

Sega 32X prices, all games & how to spot a fake

An odd, ambitious Sonic spin-off with a tethered-partner gimmick that critics split on, and one of the more expensive US 32X carts.

Sega developed and published Knuckles' Chaotix for the 32X; it came out in Japan as Chaotix. Knuckles teams up with a partner connected by a tether that behaves like a rubber band, and the player has to use it to maneuver both characters. The game was planned as a Sonic game for the Sega Saturn before it moved to the 32X, whose power allowed dynamic sprite scaling and 3D polygons in the special stages.

Reviews were mixed. The four reviewers of Electronic Gaming Monthly praised the graphics and thought it one of the best 32X games, and GameFan called it the best Sonic entry since Sonic the Hedgehog 2. GamePro and Game Players felt it did not push the 32X, citing missing graphical effects and Genesis-quality audio, and Game Players dismissed it as a cheap attempt to put the Sega mascot on screen.

“The best game lor the 32X has arrived. As expected, Chaotix breaks new ground in several areas.”
— GameFan, May 1995

“An enjoyable platform game that'll go down well with Sonic fans but it’s certainly not the type of ground-breaking 32-bit experience that people bought the Megadrive 32X for.”
— Sega Magazine, June 1995

“want to test drive before you buy. It has some cool features and many characters to use, but it doesn't hold my attention for very long.”
— Game Informer, June 1995

“It’s pretty, but as a 32X release, it just doesn’t seem like a significant advance over a Genesis game.”
— Electronic Games, July 1995

Worth knowing

Saturn plans. It was originally planned as a Sonic game for the Sega Saturn before development moved to the 32X.

Before you buy

Among US 32X games this is one of the pricier carts. Reproduction carts of it exist and are discussed openly by collectors, and one collector described putting repro boards into Acclaim 32X cartridge shells with new labels, so a genuine-looking 32X shell does not prove the cart inside. Ask for a photo of the label and of the board, and buy from a seller who accepts returns. The European cartridge usually costs about the same loose and noticeably more complete, while the Japanese copy costs somewhat less loose and about the same complete.
