Shadow Stalker is a cancelled 2D side scrolling action game that was in development in 1993 by Athena for the Super Nintendo / Super Famicom. From the few screens preserved in the gallery below (scanned from Console Plus #24, EGM #51 and Game Power #25), we can assume that the game was probably going to play similar to Shinobi / Ninja Gaiden, but with lots of huge robots and other mechanical enemies.
Thanks to Alex and Celine for the contributions!
