Hi nineko. I haven't heard from you in a while. The Knuckles areas in the Sonic 3 levels are complete structurally, but the object placement was clearly still being worked on. There are some interesting changes between Sonic 3 alone and Sonic 3 and Knuckles in what got put where. I'd show every image I have on this, but I think the image count is over 100, so I'll just point out the more interesting stuff. I'm sure this has been brought up before, but I've looked around and I haven't found any detailed documentation on it. If anyone has a link to a site with this information on it, I'd love to have it. Pictures from Sonic 3 are on the left, S3&K on the right. Angel Island Zone -------------------- Yeah, very temporary object placement. Obviously in the final game they wouldn't put a lamp post in the middle of two breakable pillars, and they certainly wouldn't put one about two fucking seconds into act 2. Oh, and the spikes are gone in S3&K. This is also the only lamp post in Knuckles' area in Sonic 3. Hydrocity Zone ----------------- *No rings or lamp post in Knuckles' section of Hydrocity Act 2. Marble Garden Zone ----------------------- Knuckles' last section before the boss has its difficulty ramped up slightly. Oh no, a badnik! The oh so difficult "wait until you can jump onto the platform and spindash through the wall" has been replaced with one of those arrow shooting Incan head things. Carnival Night Zone ----------------------- Act 1 has some badniks and rings added to it in the final -- there aren't any badniks at all in Knuckles' sections. Other than 5 rings near the start and 14 rings near the end, Knuckles' Act 2 section is completely barren of all objects. Ice Cap Zone ---------------- Act 1 has some object shifts in the dreaded spiky ice ball portion. Other than that and 3 rings above Knuckles' sign post at the end of the level, everything is the same. Act 2 has some more shifts/additions/deletions in objects, but nothing major. Launch Base Zone --------------------- The amount of objects changed in Sonic and Tails' sections of Launch Base Zone are so numerous that I can't be bothered pointing them all out in this post. The S3&K versions have been drastically toned down in difficulty. I'll move on to the Knuckles portions. Launch Base Zone Act 2. The floating platform above the spikes (well, embeded) was replaced with a spring that would launch you into the speed booster, sending you back into the turbine. If you let yourself fall while you're on the platform... ...you'll end up stuck in the floor. Glad this went out. Notable because this is the only other time those particular breakable blocks show up in the game. In S3&K they're only present to keep Sonic out of Knuckles' final boss area. -None of the rings on slopes in Launch Base Zone are present in Sonic 3. They were all added in S3&K.
