you can in s3&k by beatining lava reef but you have to cheat for sonic 3
Cream the Rabbit is unlocked after defeating Gemerl in Cyber Track (Zone 6) Act 3 with Sonic as the leader.
You have to collect all the Chao in each zone (there are 10 hidden in the 3 acts in each zone, plus one on the zone map. You can find how many are in where by going into the Sonic Factory and going into the Chao Garden and pressing select). Then, you need to go into act one of that zone and collect the special key. Then, find the special spring somewhere on the map, and that will take you to the special stage. If completed, you get a Chaos Emerald. There are Seven in all. Once all Chaos Emeralds are found, Complete Final Zone with Sonic as the Leader and you will be taken to the Extra Zone with Super Sonic.
grow up and get a life, stop playing babyish games
The differences: Super Sonic: 1) He only flashes yellow and that's when you got all Chaos Elemards *notice that the note says "Now Sonic can be Super Sonic" Hyper Sonic: 2) He flashes multiple colors and that's when you got all Super Elemards *notice that the note says "Now Sonic can be Hyper Sonic" (In Sonic and Knuckles/ Sonic 3 and Knuckles/ Sonic 2 and Knuckles, you need it to play Doomsday Zone or Game over to you! Expect for S2&K) That's all for now on!
You must be talking about Carnival Night Zone. I've had the same problem. All you have to do is find your way through. When you get that specific room with the barrel all you need to do is press up and down but don't press it up and down too much or you'll get squashed!
You have to have the genesis game called "Sonic and Knuckles". This cartridge is special because it allows another cartridge to be placed on top of it. You place "Sonic 3" on top of "Sonic and Knuckles" and you get to play as Knuckles. Same goes with "Sonic 2".
Metropolis Zone
you have to play as sonic in zone 2 act 3.
With sonic as leader beat zone 2 act 3, and he appears after you fight gemerl. Amy is zone 4 act 3, and Cream is zone 6 act 3.
you can find chao in all of the main worlds the only main world that did not have a chao hidden in it was zone 3 ocean base. but in route 99/zone 1, sunset hill/zone 2, toy kingdom/zone 4, twinkle snow/zone 5, cyber track/zone 6, and chaos angel/zone 7, all have chao hidden in them, in cyber track and route 99 their chao is hidden close to the big ring for the rest you will have to figure that out. well there`s at least one answer!
