Flashback to October last year and some of you may remember Silicone Knights' announcement that they were developing an X-men video game. According to most descriptions, the game would put emphasis on RPG-like elements, like player choices that effect branching storylines.
At E3, gameplay footage has been released (though it doesn't give everything, such as interfaces, it does however show the main playable characters, like Wolverine). Powers and awesome moves are also shown.
Don't get too excited, thought. Either it'll take on a comic book style like inFAMOUS, or it'll be released for the Playstation 2. Or the video was rushed; which isn't expected from a franchise such as X-Men.
