Planned initially as the SAM's very own Target: Renegade, coded by Wayne Coles, with graphics for the demo provided by Steven Pick, and to be published by Persona.
A single-screen, two-player demo seems to be all that exists, but no enemies are included, so players can only fight each other with their Greg-Proops-in-sportswear clone characters against a backdrop closely based on the opening level of Target: Renegade. Collision detection is implemented, but not fully (you can knock down with a flying kick, but only stun with punching, and sprites must be no more than 1px off vertically to make contact). It's not clear whether there was a story attached, or if the idea was to simply recreate Target: Renegade in SAM's MODE 4.
Gordon Wallis was tapped to provide graphics, and aimed to make the game closer to a flick-screen Streets of Rage/Final Fight-alike, though first drafts of both level maps and player sprites are, to this day, incomplete...
It remains to be see how much of the revised style would have been feasible.
