Welcome! If you came here expecting The Sonic 2 Beta Page, we regret to inform you that due to a combination of security holes and really the site hasn't been maintained for years, we've pulled the plug on the old standalone site. The content was already being taken from here, the Sonic Retro wiki, so those who are looking for the old content can still find it below. We apologize for any inconvenience this may cause you, but don't fret: the legacy has been living on here and will continue to do so for years to come. Trust us. We do our best, and many great things have happened as a result. We'll be there for the next Hidden Palace! - The Sonic Retro Staff
