Sonic 3 and Knuckles

Third party DRM: Steam

This game requires a free Steam account to play.


Dr. Eggman’s (AKA Dr. Robotnik’s) Death Egg was once again blasted by Sonic, crash-landing on the peak of a volcano on the Floating Island.

Dr. Eggman is still at large, and Sonic can’t allow him to get his hands on the Master Emerald and repair the Death Egg. Sonic must also keep Knuckles off his back but Knuckles has problems too. As guardian of the Floating Island and all the Emeralds, Knuckles must do his part to keep the island safe. While they’re going the rounds with each other, who will stop Dr. Eggman?

The Best Sonic, by Far

taythib | Nov. 18, 2013 | See all taythib's reviews »

Of the three original sonic titles, this is the peak. Playing as the three original heroes, Sonic, Tails, and Knuckles, run at high speeds through very atmospheric platforming levels on an adventure to defeat Dr. Robotnik. The level design is extremely intuitive while the controls feel very smooth. The graphics are perhaps the most beautiful of the era, having a colorful combination of backgrounds and enemies. Highly reccomended!


The Best of Sonic, and the Best Experience

Sonic games have plummeted over the years, I don't think anyone can argue that. The games just lack the speed and pure fun that the older Sonic's had. This game combo was the pinnacle of Sonic's greatness.

This game is near perfect with its game play, although constantly running can be boring after awhile, you'll soon find that the levels all have secrets that hold power ups, lives, and bonus stages to get the chaos emeralds and eventually become Super Sonic. This is where most of the game's difficult lies.

The stages themselves, as well as the bosses, aren't that difficult, but they aren't supposed to be difficult. The games keeps a steady pace that allows even new players to run and dash through the stages without much effort. This difficult gradually increases (around the Marble Garden Zone speed won't help you much) and becomes a pretty solid experience. But, once you slow down and begin to realize you can collect chaos emeralds and become Super Sonic, the game has a whole new element of discovery that will make you play the game again and again.

If I didn't still own both of these titles for the Sega Genesis, I'd buy them again.

The best Sonic clasic game in my opinion, my favourite, adding new elements and nice dinamic stage change, the new 3 new shields, really helpful! Overall fun, still play it sometimes to this day.


The best of the franchise

Neohoodman | March 2, 2013 | See all Neohoodman's reviews »

Sonic 3 was my first Sonic game. It introduced me to the fast world of Sonic and co. and the fun gameplay that entailed. The graphics are amazing with colorful and inspired worlds. Music sounds good and will get stuck in your head for time to come. Insane replay value, thanks to the 3 (4, if you consider Sonic & Tails together a character) different characters with all different types of gameplay. There is even a co-op possibility thanks to Sonic & Tails simultaneously playing.

If there is a single game to pick out of all of the Sonic games, it is definitely this one.


The ultimate Sonic platformer

Sonic 3 is undoubtedly the high point for the 2D sonic franchise, and ultimately it improves on the game mechanics and level design of its predescors. Sonic 3 and Knuckles diferentiates itself from other sidescrollers, particularly by the game speed, but also by the inclusion of an achivement based mini game system. Its a blast to speed through waves of enemies, and sucess in challenging minigames give a strong sense of accomplishment that is highly rewarding. Both sonic 3 and the included add-on, sonic and knuckles, feature a great music score that complements the almost frantic pace of the game, but also create atmosphere which truly capture the memorable moments of the playthrough. This package also includes multilplayer functionality, where the story-mode can be played co-operatively. A race based competitive mode is also included which can be played in hotseat. The game is quite short however, and once the game is complete, there is little in the way of replay value. Overall the sonic and knuckles is an exceptional game, and despite being short, it is well worth a look.
