Overworks was a development subsidiary of Sega created with members from an in-house Division titled Amusement Machine 7 Research & Development(AM7 R&D). It was later merged with another subsidiary, WOW Entertainment, whose name was changed to Sega WOW alongside the merger.
Sega WOW was later shutdown and reorganized back into an internal Sega R&D Division structure after Sega's merger with Sammy in 2004.
