Wolfang is an action game / side scrolling shoot ’em up that was in development by Seibu Kaihatsu (?) for the original Playstation and it would have been published by Bird (?). There are not many info about this, maybe the game was released under a different name and a by different publisher? (even if it’s not listed in Sibu Kaihatsu’s games list) If you recognize this game or have some more info, please let us know!
