"Lego Batman" is really popular; as in, sold over 11 million copies since releasing back in 2008, popular. While other Lego videogames have performed well – the "Star Wars" and "Indiana Jones" adaptations immediately come to mind – the Dark Knight's turn with virtual plastic blocks has outpaced them all.

So, it should come as no surprise that Warner Bros. and Traveller's Tales have decided to create a follow-up game. The fact that the sequel adds more superheroes into the mix – DC heroes, natch – actually sounds pretty great.

Announced by Warner Bros. this morning, "Lego Batman 2: DC Super Heroes" isn't only a mouthful of words, it's also apparently filled with more familiar faces than its predecessor. While the original game allowed you to play as either Batman or Robin, "Lego Batman 2" will also feature Superman, Wonder Woman, and Green Lantern. It's like a mini Justice League – except for some reason this Justice League is eerily mute and made of plastic.

You'll face off against the Joker, of course, but "Lego Batman 2" will also star everyone's favorite bald super-jerk, Lex Luthor. There's no indication of the game's plot yet, but I'm willing to bet it has something to do with breaking thugs into tiny pieces.

The action takes place in a "rich and expansive Gotham City environment filled with cool characters, great customization options, and plenty of surprises that families, young gamers and DC Universe fans can enjoy together," said Traveller's Tales managing director Tom Stone, via press release.

Some of the new additions to the game – outside of characters and setting – include vehicles like the Batmobile and Batwing. There's also new gadgets, like Robin's Hazard cannon, and new abilities that you would expect from the addition of new heroes, such as Superman's heat vision.

"Lego Batman 2: DC Super Heroes" has a planned launch window of Summer 2012, releasing across every major platform including Xbox 360, PlayStation 3, Wii, Nintendo 3DS, PlayStation Vita, Nintendo DS, and PC.
