Shadow Man is an action-adventure video game developed by Acclaim Studios Teesside and published by Acclaim Entertainment. It is based on the Shadowman comic book series published by Valiant Comics.

In 1888, Jack the Ripper – lamenting the fact that his ritualistic murders have not unlocked a mystical power that he believes to exist – prepares to perform the ritual upon himself at the expense of his own life. A man named Legion appears and tells Jack that the power he seeks does exist and offers to share this power with him if Jack constructs an insane asylum for like-minded killers in Deadside – the land of the dead. Proclaiming "for we are many!", Jack commits suicide.
