SEGA's lawyers have demanded that a fan remake of Streets of Rage be removed from its download site, after only a week or so of availability.
The game, developed by Bomber Games, had been eight years in the making and featured 103 stages, 19 playable characters, 64 enemies, 83 remixed songs, more than 40 cutscenes and eight different endings.
A statement on the Bomber Games forum requested that all distribution of the title cease until the legal situation was clarified.
"SEGA have contacted regarding the download hosted on this site," read the post. "While this issue is being resolved, please do not upload the game for others to download. Any links posted on this site will be removed. Thank you."
Since making the legal request, SEGA has issued a statement to Kotaku, explaining the decision.
"SEGA is committed to supporting any fans that take an interest in our games, and where possible we do so by involving them in Beta tests and other development, marketing or research opportunities.
"However we need to protect our intellectual property rights and this may result in us requesting that our fans remove online imagery, videos or games in some instances."
