Backbone Entertainment made a couple of intriguing pitches to SEGA. Images posted by a former artist show concept art for a new Streets of Rage game presented to the publisher. Axel Stone, Blaze Fielding, and Adam Hunter are showcased in the art. Amazingly, Backbone also pitched a follow-up to the SEGA Genesis game ESWAT.
On a slightly different note, artwork has also surfaced from the unreleased Gauntlet DS game. The title nearly made it out to market, but after a few publisher shifts, was cancelled for unknown reasons.
