ClayFighter's development actually has gone in deeper than you think. Here's something I discovered today:
ClayFighter 2 for the 3DO.
Special Edition, too.
Not much information exists about this upgrade of Judgement Clay aside from this print ad for the 3DO. The game was quietly cancelled because of who-knows-what.
On the topic of unreleased and prototype ClayFighter games, there's still information about the supposed Sega 32X version of Judgement Clay and the original version of 63 1/3 when it was called ClayFighter III and was planned for the M2 console.
This is a foreign video promoting 63 1/3 for the N64. But it doesn't look like the N64 version. Notice the stages. The stages are 2D as opposed to being 3D-rendered. This could indicate that this is the M2 version.
Finally, Sculptor's Cut has some yet to be uncovered stuff. Back in Decemeber 2017, someone uncovered a special for the Zappa Yow Yow Boyz that is done with F,B,F,P. The move is an infinite, which could be why it's not mentioned anywhere else. The Boyz have more claytalities than just the Kettle Drop. Someone uploaded a video of all the Boyz's claytalities on Dailymotion a long time ago, but the video is no longer up. The commands for those moves are unknown (and it's impossible to find them out because you can't turn off the claytality timer in SC and the L and R buttons became wavedash buttons which makes doing claytalities a pain in the ass), and Lady Liberty has one more claytality that nobody knows how to do or what it looks like.
In short, we need all the help we can to uncover more about ClayFighter!
