Sonic & Knuckles (Sega Genesis)

Who would of thought of putting a sega cartridge on another one would give you an extra charater? You can do so much in the Game. So FUN!!!

This game was one of the most innovating gaming technologies introduced during the cartridge era of video games. In a way, it is similar to the expansion packs that have become very popular in PC gaming. To my knowledge, the "lock-on" technology was never duplicated outside of cheat cartridges.

There are four different "modes" that this cartridge can take:

1) Standalone. Play as Sonic or Knuckles through several well-designed and beautiful levels.

2) Lock on to Sonic 3. Integrates the Sonic and Knuckles levels into your Sonic 3 game, and allows you to play as Knuckles! When used in such a fashion, you can take advantage of save games and it also allows you to play as Tails in the Sonic and Knuckles levels. Very cool!

3) Lock on to Sonic 2. Re-experience the levels of Sonic 2 with Knuckles. Knuckles' abilities make this a very new experience.

4) Lock on to any game (other than Sonic 2 or Sonic 3), and press A+B+C. You can play the blue sphere collection minigame, with boards based on the cartridge you put in.

All of these features are guaranteed to please any Sonic the Hedgehog fan.

This is by far the best sonic games in the series. There just so much new things you can do in the game that was not offered before.one of the main things i liked was the fact you could plug in you sonic 3 game in and finlly get to play as knuckles and explore new areas in the game. It had great sound and graphics.

This expansion made it possible to play all the Sonic games except for sonic 1 with Knuckles. Knuckles is the best character because he can glide and climb walls, making it easier to get rings and find secret areas, plus he looks cool.

I didn't find any of the other Sonic games on Sega the least bit playable, but this one, whoa! The first 3 levels are as addictive as any game on any other very old system. You have 2 choices, either Sonic or Knuckles. To me, Sonic is more fun to play with and the game is more addictive, too. Knuckles has better abilities and the game is a bit more challenging. It also has secret levels and more than one way to complete each level. I've gotten as many as around 200 rings in any one level, get a 100 rings and get an extra life. There are also secret places to gain secret lives, powerups, special attributes, and multiple coins. Sonic & Knuckles is a whole lot of fun, but you'll have to use some trial and error and have a good memory to master every single secret that it has. It has so many. This game also starts out easy and gets a bit harder with every level. This game, while not quite as good as Mario, gives Mario a major run for its money. If, by chance, you liked any of the previous Sonic games, then you'll love this one.

i bought this game for my bf for valentines day. since he collects games and game consoles. he loved it. he didnt have it. it was a little dirty but he cleaned up and it worked fine.

This is a great Sonic Game...you can play as Sonic or his rival Knuckles. They both have their own styles (knuckles climbs walls). The graphics are updated a little in this version but the story line is basically the same as the other Sonic games. If you like Sonic this is a great play...

You can lock-on to your sonic the hedgehog 2 game and play as knuckles with all of his signature moves.

just like the rest of the reviews say, it adds a 'whole new game'. It is the second half of Sonic The Hedgehog 3. The whole gme was intended to be on one cartridge. Locking on Sonic The Hedgehog with Sonic & Knuckles enables you to play in 500 levels of the 3D special stage, you can choose between Sonic or Knuckles. Locking on Sonic The Hedgehog 2 will bring you Sonic The Hedgehog 2, only you get to play as Knuckles. Everything else is the same in the game, only some of the cheat codes are changed and you can't play in 2-player split screen mode. Difficulty is harder in the game due to Knuckles not being able to jump as high as Sonic & Tails can. Locking on Sonic The Hedgehog 3 brings you the complete, true storyline that the game is all about, yet the rest is up to you to see the proper good ending. In Sonic 3 locked onto Sonic & Knuckles (Sonic The Hedgehog 3 & Knuckles, or S3&K for short) gives you the ability to experience more levels, full gameplay, and extra goodies. All Sonic 3 and Sonic & Knuckles levels are joined together, where launch base zone (last level of Sonic 3 which is zone 6) crosses over to Mushroom Hill zone (first level of Sonic & Knuckles which is in this case, zone 7). As usual, the chaos emeralds play a part in the game, but in S3&K, there are also Super Emeralds to collect, giving Sonic & Knuckles the ability to transform into a level of power greater than that of their super form from just the chaos emeralds, they get to experience 'Hyper form' or better known as Hyper Sonic & Hyper Knuckles. However, Tails cannot utulize the power of the chaos emeralds, and can only turn into Super Tails by aquiring all sets of the 7 Chaos and 7 Super Emeralds. Sonic's power in Hyper form gives him invincibility and the ability to double jump. At the instance of when Sonic starts his second jump, the whole screen will flash white for a split second, and will destroy all of the enemies in the screen. Knuckles power in Hyper form gives him invincibility and the ability to shake the walls and kill all of the enemies in the screen. To do this, just simply glide into a wall, but you need to start at a distance or have a bit of speed when gliding into the wall. Tails's power in Super form gives him invincibility and the ability to fly faster and have flickies (or just simply yellow flashing bird friends) following him and they peck the enemies to death (just one hit). The other feature that S3&K gives you is of course the ability to save just like in Sonic 3, but also adds 2 additional save slots, and the ability to save your continues as well as your lives. 2 player competition is the same as in Sonic 3 not being locked onto Sonic & Knuckles with all 3 characters available. This game (S3&K) lets you play as Sonic & Tails, Sonic alone, Tails alone, and Knuckles alone.

In order to go to doomsday zone (zone 14) you will need either the 7 Chaos Emeralds. Super Emeralds are optional for this stage, but is better if you want the fully fleged, good proper ending.

Everything About This Item Is Good. I Would Defenetely Buy From Them Again. Game Is Like New, And Was Shipped Very Quick. Everything The Seller Sells Is Good, And Packaged.
