I’m sure we’ve all said at one point in our lives, “Wow, we have reached the pinnacle of videogaming,” only to be proved wrong a year later. Innovation is the key to ensuring that gaming franchises don’t become stale. The introduction of new characters, new features and gameplay styles are all used in attempts to keep games fresh. But what if you could add new characters to older games? Well, that’s just what the creators of Sonic & Knuckles did.
Sonic & Knuckles is a single-player platform game developed and published by Sega. It was released for the Mega Drive in 1994 and later on various compilations including:
- Sonic Jam (1997) for the Sega Saturn
- Sonic & Knuckles Collection (1997) for the PC
- Sonic & Garfield Pack (1999) for the PC
- Sonic Mega Collection (2002) for the GameCube
- Sonic Mega Collection Plus (2004) for the PlayStation 2, Xbox, and PC
- Sonic’s Ultimate Genesis Collection (2009) for the PlayStation 3 and Xbox 360
- Sonic Classic Collection (2010) for the Nintendo DS
The game would also become available on the Wii’s Virtual Console, Xbox 360 Live Arcade, and Steam. For this review, I played the version found on the Sonic’s Ultimate Genesis Collection (2009) for the PlayStation 3.
No sooner had the events of Sonic the Hedgehog 3 (1994) been concluded, where once again Sonic thwarted Dr. Robotnik’s evil plans to steal the Chaos and Master Emeralds causing DeathEgg to crash land on Floating Island (Angel Island), Sonic must again act quickly to seek out the emeralds and recover them before Dr. Robotnik can find them. However, Sonic is now fighting a war on two fronts. He also needs to beat Knuckles to Echidna to them too. Knuckles is the Guardian of Angel Island and the Emeralds, and his mission is to stop any invasion by any means necessary.
You can choose to play as Sonic, Tails, or Knuckles in this game. Sonic and Tails have the same skill set as before. However, if you play as Knuckles, you may not be as fast or be able to jump as high as Sonic, but you do have your advantages. For one, you can glide! Secondly, you can climb walls using the spikes on your fists.
As is standard for Sonic games, you collect rings along the way. When you gain 50 rings you can enter the special and bonus stages. These are identical to those found in Sonic the Hedgehog 3 (1994) in that you must run around a globe and collect small blue spheres. The more you collect, the faster your run making it more difficult to control.
Another bonus stage is similar to the emerald stages of Sonic the Hedgehog (1991) in that Sonic is curled up in a ball and must navigate a rotating stage. The aim is to stay as central as possible and enter a slot that spins fruit machine reels to win rings. This continues until you touch the outer edges a few times revealing red circles in the wall that make you exit the game when you land on them. As before, every 100 rings you collect gains you an extra life.
A third bonus stage sees you use glowing electrical spheres to catapult yourself up the screen. However, you need to be quick. A horizontally spiralling laser beam slowly moves up the screen. if you fall into it, you will exit the bonus stage.
Sonic & Knuckles must traverse the following levels:
Mushroom Hill Zone
Flying Battery Zone
Lava Reef Zone
Hidden Palace Zone
Sky Sanctuary Zone
Death Egg Zone
Throughout the levels you must try to find the Chaos Emeralds. As with Sonic the Hedgehog 3 (1994), these are found in hidden locations. Once you obtain all the emeralds, you gain access to special abilities.
The power-ups are exactly the same as found in Sonic the Hedgehog 3 (1994). The boxes contain:
- Super Rings – 10 rings
- 1-Up – Extra life
- Invincibility – Invulnerability for a short time, however, you can still die if you are crushed.
- Water Shield – Allows you to breathe underwater as well as bouncing on the heads of the badniks.
- Lightning Shield – This magnetic shield attracts rings when nearby, can absorb energy ball attracts, and allows you to gain a little extra height with a double jump.
- Flame Shield – Makes you impervious to lava and fireball attacks. You can also briefly turn into a fireball that will destroy badnisk.
- Super Shoes – You can run at hyper speed for a short period of time.
- Robotnik – Avoid these as they spell instant death if you break them.
One of the biggest selling points of this game was that the cartridge was designed for you to attach Sonic the Hedgehog 2 (1992) and Sonic the Hedgehog 3 (1994) onto the top of the Sonic & Knuckles (1994) cartridge allowing you to play the previous games with Knuckles. This isn’t just a quirky feature either. It actually allows you to reach previously unattainable areas of the levels.
Although the gameplay is unchanged from Sonic the Hedgehog 3, the game has added a few nice touches to make the gameplay a little more interesting. An example of this can be found in Sandopolis Zone 2 where you need to pull down bars to light up the level. When the lights start to dim, you will begin to be attacked by ghosts and so you need to find more levers to pull down to scare the ghosts off.
Graphically, you can’t fault this game. Colourful, vibrant and detailed backgrounds, and gorgeous looking sprites. The levels have some nice touches too, such as Mushroom Hill Zone when you land on the green ground and what looks like yellowish pollen balls fly up.
The theme tune is the same as Sonic the Hedgehog 3 (1994), and the music throughout the levels continue to be of a high standard as we have with previous Sonic games.
The replay value of the game is certainly there too. Not only do you have to ensure you gain all the Chaos Emeralds to earn the good ending, but some of bosses are different depending on if you play as Sonic or Knuckles which certainly warrants a play through as both characters.
My only criticism of the game is that I question whether the format is now becoming a bit stale. This is Sonic’s fourth instalment, ignoring Sonic Spinball (1993), and it feels like it’s the same game being rehashed over and over again. I appreciate that Sonic the Hedgehog 3 (1994) and Sonic & Knuckles (1994) were originally meant to be one big game, but one could be forgiven for wishing Sonic the Hedgehog 3 (1994) had added something to differentiate itself more from Sonic the Hedgehog 2 (1992). Whilst the adding of a new character and creating a system where it can be played on older Sonic games is ingenious, I just think the format of the game needs a good shake up.
Did I complete the game?
Yes, I have completed the game with both Sonic and Knuckles and with both obtaining all the Chaos Emeralds.
What the critics said:
Computer & Video Games: “It’s over a year old now and you need to buy both Sonic 3 and Sonic and Knuckles to fully enjoy it. That’s why it’s here at the bottom. But in truth, Sonic 3 and Knuckles is the best platform experience ever. It’s what video games were invented for. Overall 97%“.
Electronic Gaming Monthly: “Sonic and Knuckles is the ultimate Sonic game. This is the best game of the series and the lock-on technology offers new life to older games. Many new games can be plugged in, too. Fantastic graphics, sound and game play make this Sega’s ultimate game and it gets my vote for Genesis Game of the Year! Overall 37/40“.
Game Pro: “Sure, sure, it’s just another Sonic game. But this one’s got some revolutionary elements that make it another ground breaker for Sega. Overall 20/20.“
Next Generation: “A slot in the top accepts previous Sonic carts and enables you to play them starring Knuckles instead of (yawn) Sonic. Does this make Sonic 2 less Tedious? Well, no. But it is an impressive technical feat and if it points to a future where old games can be given a new lease on life with “mission carts” similar to the expansion disk that have long been available for PC titles, then NEXT Generation is all for it. Overall 4/5“.
Sega Magazine: “Slick and accomplished platformer which doesn’t quite catch the edge over the younger, fresher Headdy. Overall 92%“.
Sega Power: “Excellent ideas, great game. A change in gameplay is needed soon. Overall 90%“.
“Another winning instalment from Sega. Fun, fast and furious, with great new bonus stages, plenty of replay value, and stunning graphics. I just fear that the format is begininng to grow stale. Let’s try something different next time.”
