Knuckles.exe: The Emerald's Curse Eggman Demo

Version: 1.0.08 months ago
Eggman Demo

One day, while at Hidden Palace, Knuckles kept feeling a weird energy. Bothered by it, Knuckles went to Sky Sanctuary to figure out where it was coming from. Little did he know that'd be his worst and possibly last mistake.

Basically take on sonic.exe except it's knuckles who's evil.

Also my first sonic.exe game so prob not the best but It's hopefully still pretty good.

If you encounter any bugs let me know and i'll try to fix them.

No. This game is not a virus if you're wondering

Yes. I know this game isn't scary idc

Also This game is done purely for fun, don't ask me where this fits in the sonic canon cause I never thought of that before making this game. So I guess technically this game is it's own universe I guess

You should join since i'll prob post teasers and stuff on it

....yea no this ain't happening

There's 2 bosses left to make and the last duo ending is done. (I say 2 bosses but that also includes their continues, give ups, and cutscenes that follow them so it's not exactly a small amount of stuff left to do.)

To everyone who said "The Sonic & Tails Duo is basically sonic 3"

uhh new teaser. The status of this ending is prob 40% as of now since I see a lot of you asking
