Sonic must defeat doctor Robotnik yet again. This time, Robotnik wants the Master Emerald, the biggest and most powerful of all the Chaos Emeralds. With this emerald, the Death Egg, Robotnik's ultimate weapon will have limitless power and nothing can stop him from taking over the world. It's up to Sonic to stop Robotnik's plans, but he's not the only one. Knuckles, guardian of the Floating Island and the Chaos Emeralds tries to stop him as well.
Play as both Sonic and Knuckles in 8 new zones in two different adventures. Get as many rings as you can, get all the emeralds and defeat enemies. The original cartridge could be combined with Sonic 3 to play the game as it was meant to be played. When combined with Sonic 2, you were able to play it with Knuckles for a new game experience.

Sonic and Knuckles is awesome game, I still have the original cart for the Genesis, but I might get this as well for some odd reason, I'm sure it'll be a few months before they release it though, glad to see they released all the classic Sonics on the VC.

All the Sonic side scrollers for Genesis were awesome. This one is no different. I always liked the first Mushroom level because it was trying to rip off Mario.

I personally think you should be able to download the enhanced versions of the previous games as a seperate channel for free but only if you already downloaded Sonic & Knuckles and whichever previous game you want to play enhanced.

Wasn't this game on the 32x or cd or some stupid add-on for the mega drive? And Im not thinking of Sonic CD.

Hopefully they'll make something that will let you combine this and sonic 2/3 to play sonic 2/3 with knuckles instead of seperate releases.

Not really, Tony. But it is a little like it.

11 Mar 2008, 14:48 GMT
No it wasn't, Csh. It was for the regular Genesis; it just had a different shaped cartridge allowing you to put other cartridges on top.

I've never played this before. Does Knuckles handle differently as a playable character? Just curious....no matter what, though, I'm sure this is a great game!

knuckles is really similar, only difference is gliding, he cant jump quite as high and knuckles can climb on certain walls

Deadly game, I remember I bought this on its release. Id imagine Nintendo would sort it so we have access to the full sonic3 and knuckles experience. After all, once locked on, extra zones and bosses were opened up at the end as well, and we dont deserve to miss out on them!

18 Mar 2008, 23:20 GMT
I only have sonic 2 at the moment but i am sure the addition of knucles to sonic 2 would be good.. this game alone is awsome never mind the add ons it gives you.. totally worth 800 points..

It means that it is either...
1. Has just been confirmed that it is coming to VC
2. Has just been released
In this case, it means number 1

So if this was released which sonic game would i need 3 or 2.. I have the second sonic game..
27. Mr. Cheez

I wanted to download Sonic 3 for a while, but not until this game gets released. Wonder how they are going to handle that lock-on technology? All I know is I'm not charging 1600 Wii points on both games, that's fer damn sure.
28. Bass X0
03 Jul 2008, 10:33 GMT
I still think S&K will be sold at 800 points. And if you download S&K and already own one of the games that could lock on to it, you could download the locked-on version for free.
29. Terranigma
03 Jul 2008, 10:35 GMT
Or at a small charge, knowing Nintendo. If so, then hopefully, it would only be like 100-200 points.

Come on Nintendo, U know u guys have 2 include the lock-on feature somehow.

I have this on the Sonic Mega Collection, along with the add-on games, though you have to unlock them by beating Sonic & Knuckles and the game you want added on, and let me tell you, that is no easy task. Those games are Blinkin' hard! If you just want the lock-on games, don't go with the Mega Collection. Of course, Ninty will probably make you buy both games to get the lock-on game, if they don't make you pay for them idividually that is.
32. Surgical Precision
10 Jul 2008, 05:46 GMT
Ugh... You just know they're there gonna Street Fighter 2 this thing into the ground...
One can hold out hope, But this is SEGA!!! we are talking about...
At times I honesty think they're worse then Capcom...
And yet... WE'RE STILL BUYING THE DAMN THING!!
Ugh... Well... Must mean it's good... Right?...
33. Mickeymac
10 Jul 2008, 07:11 GMT
@Surgical Precision
My favorite old-school Sonic game, actually, considering I didn't get to play the Lock-on games. Hardest one, too, in my opinion.
34. Surgical Precision
12 Jul 2008, 03:40 GMT
Sonic 3 & Knuckles aka Sonic 3 Complete is a MUCH more well... Complete affair...
I know S&K is good but if you can help it, Hold off until they release the whole game instead of just buying it in its two halfs...
They're likely gonna re-release Blue Spheres next followed by Sonic 2 with Knuckles before they bring the complete game out...
You know... To justify those who will buy the game in two halfs & drive those who didn't to the brink of insanity until they eventually crack & do buy the game in two halfs exactly one week before they release the whole one!!
35. Mickeymac
12 Jul 2008, 07:46 GMT
@Surgical Precision
I already have the Mega Collection, so either way I'll save my money, even if they do make you unlock all of the games.
36. Surgical Precision
12 Jul 2008, 21:11 GMT
Oh... Well... Right then... What the HECK was I thinking... ?...
Anywhoo... Well that's an easy fix...
Simply play Sonic 3 & Sonic & Knuckles 50 times each to unlock Sonic 3 & Knuckles...
"How the hell is THAT easy!" You say?... Simple...
All you have to do is select the game let it load past that blue screen (Before the game itself loads, Just wait for the sega logo if your not sure) and congratulations! You just "played the game" one time...
Repeat that process as many times as needed & you'll have the game unlocked probably within 10min!
37. Mickeymac
13 Jul 2008, 23:29 GMT
Whoa, that easy? I'll be right back!
Edit: Even Easier! I only had to play Sonic 3 30 times and Sonic & Knuckles 10 times. I'm gonna try and unlock Sonic 2 & Knuckles now!
Edit again: Okay, I shouldn't have tried that before I consulted Gamefaq, because I played Sonic 2, Sonic & Knuckles, and Sonic 3D Blast until the Game log stopped recording, yet I got nothing. I'm trying Sonic 1 now, and I only stopped to go to the bathroom, then write this. Ya know, I had heard the cheat before, but the numbers were so inconsistent that I didn't believe it to be true, but now that I've seen it happen before my very eyes, I'm mystified. I can't wait to unlock more games!
Edit thrice: Well, I unlocked something - Blue Sphere. I don't know what it is, but I got it. I'm trying Spinball now.
Edit Perfect: Yeah, I really should've checked Gamefaq(I have it bookmarked for G-D sake!) first before I tried on my own, as I only had to play Sonic 2 20 times instead of my 50, Plus playing Spinball 20 times(16 in my case); I only needed to play 3D Blast 20 times, yet I played it 40 times, plus Sonic 1 20 times(14 for me); Those 40 extra plays of Sonic & Knuckles were absolutely unnecessary. In short, I unlocked all of the Lock-on games from Sonic & Knuckles - Blue Sphere, Knuckles in Sonic 2 and Sonic 3 & Knuckles. I simply got them the hard way.
Only one thing left to unlock - Ristar. I'm not going to, since it's far too much of a hassle, considering I could buy the Sega Genesis Collection and play it on that without any hassle, though I would prefer to play it with a Gamecube controller, since it has more of the feel of the Genesis Pad.
38. Surgical Precision
14 Jul 2008, 03:12 GMT
Nice!
Also the gfaq section about sonic gems collection is accurate as well... I don't know if you have that one or not but it's normal way of unlocking things would take you weeks to finnish...
Anywhoo... Enjoy Sonic 3 & Knuckles! Best of the old school Sonics without question IMO...
It was the first Sonic game on the Genesis to give you a hidden ending once you completed all 14 bonus stages...
39. PHANTOM93
22 Jul 2008, 01:48 GMT
This is a really great game, I still have the original cart. But since my Genesis (actually it's a Genesis 2 if you want to get technical) still works (and is hooked up to of all things a Commadore 64 monitor) I don't know if I'll download this when it comes out, but the audio cable for my Genesis is starting to go so I may get it.
On another note I love what happens when you put a non-Sonic game into the expansion slot! When the "NO WAY" screen comes up all that you have to do is press the A, B and C buttons at the same time and you'll get to instantly do one of the bonus stages as either Sonic or Knuckles!
40. Mickeymac
22 Jul 2008, 20:01 GMT
@PHANTOM93
Yeah, those bonus stages were crazy addictive! Not to mention mad hard too. I used to spend hours just playing that! I hope you can play that when this one is available.

23 Jul 2008, 16:18 GMT
I've got an idea for when this is released. Maybe the Virtual Console could also release downloadable modules for Sonic 3 & Knuckles and Knuckles in Sonic 2. They could be free downloads if the right games are in your purchase history - for example, if you've purchased both Sonic 3 and Sonic & Knuckles, you could download the Sonic 3 & Knuckles module free of charge to simulate the lock-on mode.
I already have Mega Collection, so I won't need it anyway.
42. PHANTOM93
23 Jul 2008, 17:37 GMT
^ Yeah that's the only way I can see multicart getting onto the VC because VC emulation is done differently than PC emulation.
43. BJDJ1234
31 Jul 2008, 23:34 GMT
A very nice download but it's best to get the sonic mega collection as you get all the Mega Drive Sonic's, better value for money/points, don't have to wait months for it to arrive on VC and you get to play the great Sonic The Hedgehog 3 & Knuckles along with Knuckles in Sonic The Hedgehog 2.

16 Aug 2008, 06:27 GMT
BEST SONIC GAME BY FAR. This game is so good. The best part of this game is you get to be Knuckles. I remember when it was on the Sega. it was weird because you would insert the "Sonic Knuckles" game and then on top of the cartrige you could insert an earlier Sonic game on top of the sonic knuckles...great, great game!
45. Bensei
21 Aug 2008, 10:01 GMT
I wonder how they'll solve the lock-on. I guess you can fix Sonic 3 & Knuckles with an update you can only access after byuing S&K. However, I wonder how they will make it with Blue Sphere and KiS2. I'd suggest making those optional free downloads too after purchasing S&K and S1/S2. Or, instead of making Blue Sphere and KiS2 own games they could add after Game Start the option link with lock-on. If you have S&K you can start the three lock-on games this way
46. MrPinguy
23 Aug 2008, 01:27 GMT
I remember use Sonic 3 on this one.
It was great
Sonic CD and Sonic 3 and Knuckles (S&K + S3) are for me the best sonic games ever.
Probably this one it will be released as a wiiware to feature the lock-on games
47. Kawaiipikachu
24 Aug 2008, 15:15 GMT
@MrPingGuy
i had that same thought as well a WiiWare remake with ehanced diffenition graphich's added features ect plus it will emulate the lockon feature with the same ehancements as well .

If i did not already have the Sonic Mega Collection then i would be getting the Sonic Genesis Games including this one but i have the SMC so i won't be getting it but at least it is a game you should indeed get even if you only get them through the VC.
49. BJ
14 Nov 2008, 14:12 GMT
Sonic and Knuckles is a great game but it's a little boring when you don't combine it with Sonic 3. Still a good game to get.
