The LEGO Group is entering the virtual toy world with LEGO Dimensions, a new line that merges video games with LEGO minifigures and building sets.

The gaming franchise is being developed by TT Games and published by Warner Bros. Interactive Entertainment, in partnership with the LEGO Group.

LEGO Dimensions will launch Sept. 29 with starter pack that includes a "LEGO Dimensions" video game; the new LEGO Toy Pad, which allows players to "transport" physical LEGO minifigures and other objects into the video game; bricks to build the LEGO Gateway; and three LEGO minifigures including LEGO Batman, LEGO Gandalf and Wyldstyle, as well as the LEGO Batmobile.

“When kids play with LEGO bricks, they build beyond the singular brands, intermixing all of their favorite characters and universes, and we have come up with a way for players to experience that in games,” says Jon Burton, founder and creative director, TT Games. “Now for the first time in a video game, LEGO fans can play in the virtual world and in the real world–combining everything without restrictions. Imagine putting LEGO Gollum from The Lord of the Rings behind the wheel of the LEGO Delorean in New Ninjago City–the creative play is endless.”

The "LEGO Dimensions" game will bring together a number of LEGO universes including DC Comics, The Lord of the Rings, The LEGO Movie, The Wizard of Oz, LEGO Ninjago, Back to the Future and more, as characters join forces to battle in worlds outside of their own.

“LEGO Dimensions is unlike anything that we have ever done," says Niels Jørgensen, vice president, digital games, the LEGO Group. "It further extends the LEGO play experience into the digital world with all of the characters, humor and action of LEGO video games now combined with the fun of LEGO minifigure and model building. We are thrilled to expand our partnership with TT Games to explore ways in which physical and digital LEGO play can merge in meaningful ways for children.”

Expansion packs will also be available at launch with additional buildable characters, vehicles, tools and gadgets, as well as game content such as mission-based levels and in-game abilities. Packs that will be available this year include the Back to the Future Level Pack with a LEGO Marty McFly minifigure; three The Lord of the Rings Fun Packs with LEGO Gollum, LEGO Gimli and LEGO Legolas minifigures; and a The Wizard of Oz Fun Pack with a LEGO Wicked Witch of the West minifigure, among others.

"LEGO Dimensions" will be available for Xbox One, Xbox 360, PlayStation4, PlayStation3 and Nintendo Wii U.
