3D Realms has shut its doors, and now Take-Two, who'd been planning to publish Duke Nukem Forever, is suing for breach of contract. According to Bloomberg, the GTA publisher is suing Apogee Software, a 3D Realms-related entity which is the current rights-holder, claiming the studio's closure terminated development on the game -- which has been ongoing since 1997. "Apogee continually delayed the completion date for the Duke Nukem Forever," says Take-Two in the complaint. "Apogee repeatedly assured Take-Two and the video-gaming community that it was diligently working toward competing development of the PC version of the Duke Nukem Forever." Take-Two says it paid $12 million for the publishing rights to the game all the way back in 2000, an agreement it renewed in 2007. At the time, developer 3D Realms had indicated that it planned to complete Duke Nukem Forever in 2008 -- but later backed off that statement. When 3D Realms' closure was announced last week, Take-Two noted that it still owns the publishing rights to the game, and that its agreement never included funding for development.
