What if the myriad worlds of Lego were to cross-over into one giant adventure? That's the question that Lego Dimensions is here to answer with inevitably awesome gaming.

Lego Dimensions is a new way of experiencing Lego both in the real world, building, and in the gaming world, playing. In the computer game you take control of Batman, Gandalf and Wyldstyle travelling across worlds to stop a "bad dude who wears a helmet" and is tearing riffs between the Lego worlds.

As the trailer shows the game story appears to be interspersed with real world Lego building.

Lego Dimensions crosses the worlds of Lego Wizard of Oz, Lego DC Comics, Lego Lords of the Rings, Lego Back to the Future and more.

On top of the game there will also be a Lego Dimensions Starter Pack that includes: the Lego Toy Pad, which allows players to transport special Lego minifigures and other Lego objects into the game, bricks to build the Lego Gateway, three Lego Minifigures, including Lego Batman from DC Comics, Lego Gandalf from The Lord of the Rings and Wyldstyle from The Lego Movie, plus the Lego Batmobile.

Lego Dimensions will be available from 29 September on Microsoft's Xbox One, and Xbox 360, Sony's PS4 and PS3 and Nintendo's Wii U.

"When kids play with LEGO bricks, they build beyond the singular brands, intermixing all of their favourite characters and universes, and we have come up with a way for players to experience that in games," said Jon Burton, Founder and creative director, TT Games.
