I've been scouring Google for hours and can find nothing more than a passing blurb about its cancellation. There isn't even anything available on Deep Water!
Anyone know where I can find something?
IIRC Deep WAter was an in-house team just for the EC development
as far as i know EC only made it to sega CD after the genny version
You can find some info on the sega-saturn.com page, on their Save Eternal Champions page, and on their june 1996 news section.

You can also find a preview picture of the game on the original box of the Sega Saturn Console...
*Glad to see I'm not the only Eternal Champions fan remaining...
Good luck !!!
