Metal Sonic 3 & Metal Knuckles

A Work In Progress for Sonic 3 A.I.R

Progress Report

In Development - 30% finished

Whats this?

I want to replace all the characters with their robotic counterparts (ie, metal sonic, tails doll, mecha knuckles, eggrobo). Metal sonic will be the lowest priority, since there already exists a amazing metal sonic mod with custom moves by BlueStreakMods. It'll obviously take a long time for it all to get done, but as I go I'll separately upload the parts as previews. (The more detailed post is here, this is just the wip page)


So far skin wise I'm just working on the Tails Doll sheet, but as the image above shows I already have plans on what  Mecha knuckles will look like. Otherwise I have all the move ideas planned but haven't started getting that side of things in motion. For things like replacing Eggman with Eggrobo I will need a lot more time with to figure out how to do that (but if anyone reading wanted to offer their help with that I'd greatly appreciate it). And finally for custom zone palettes I also have no clue what I'm doing and what I said for Eggrobo applies here as well.

Please Help!

If you think this is cool and have anything to offer help wise I'd gladly appreciate it! I've already got Lave sIime and JimmyCablesYT who said they'd help and I'm more than happy for anyone with ideas to contact me on discord (Heavily_Sinful#0196) to talk.
