Here's a new pair of Superman Returns trailer screenshots that came along with a fact sheet, which is summarized below;

The Authentic Superman Experience
True to the fiction in every respect, this is the game based on the Superman universe that fans have been anticipating for decades.

Metropolis Comes to Life
From excited citizens stopping to take your picture as you fly overhead to the traffic on the streets, every detail of this vibrant city has a mind of its own. These 80 square miles are brought to life for the first time in a videogame.

Huge Open World
Go anywhere and do anything in Metropolis as Superman. Non-linear gameplay allows you to explore and play the game exactly how you want to at your own pace. Where and how you fly – to the top of skyscrapers, dodging elevated trains – is completely up to you, since gameplay is designed as a true open world experience.

Missions and Mini-games
With notorious villains like Metallo and Parasite, and colossal challenges only Superman can overcome, you must navigate the Man of Steel to monitor and protect Metropolis from destruction.

Varied Gameplay
Three distinct types of gameplay — Flying, Rescue, and Combat — will keep the action constant and the challenges relentless. Play both film-inspired missions as well as original content created exclusively for the videogame.

Next-Gen Technology
Graphics, sound, and gameplay have been taken to the next level to create a Metropolis like you've never seen it, with three dimensional sound, a complete orchestra soundtrack, and Oscar-wining sound designer

Superman Returns the video game will be released around the same time as the movie on PS2, Xbox and very probably next gen consoles. The movie is scheduled for June.
