Rockstar Games parent company Take-Two has addressed the progress of its long-in-development and mysterious action game Agent. Speaking during a post-earnings-announcement call recently, Take-Two chairman and chief executive Strauss Zelnick said, "We haven't announced anything about [Agent] yet." Agent remains a mystery.

　　Last summer, the first images of Agent (right) surfaced, courtesy of a Rockstar North environment artist. The visualizations showed a single character and indoor environments from the game, but nothing else.

　　Agent is a PlayStation 3-exclusive espionage title set in the 1970s. It was first revealed in 2007 and later detailed at the 2009 Electronic Entertainment Expo.

　　When the game does ship, it will do so with high expectations. In 2009, Take-Two president Ben Feder told GameSpot that Agent is being groomed to be the next Grand Theft Auto.

　　"It's the A team working on an AAA title," he said. "I think the subject matter, the characters, the story, the environment, the background--all the elements are there. It's such a rich environment to play in."
