Announced in March 1997, 7th Legion was a 64DD game to be co-developed by DMA and Epic Mega Games, the latter being responsible for the PC game of the same title. It was announced that the 64DD version wouldn't be a straight port of the PC version, but in fact a brand new game.

Along with the worldwide release of the 64DD, 7th Legion vanished into the horizon, never to be heard of again...

I haven't been able to find any viewable proof (screenshots) of 7th Legion, so question is if it ever got any further than a game concept script.
