3D Realms head honcho George Broussard finally released an "official" statement in retaliation to Take-Two Interactive's recent lawsuit, claiming that the development studio has not closed, and doesn't plan to close any time soon.
This was the first real statement made by the studio since word of its closing surfaced weeks ago. Many have speculated as to what happened to its alleged demise, ranging from a re-surfaced fictional story surrounding a 12-year conspiracy to rumors that the company ran out of money developing the infamous "vaporware" PC game, Duke Nukem Forever.
