What you might call a "block party"

In conjunction with the launch of LEGO's Ninjago construction sets, Warner Bros. Interactive Entertainment has announced that a sequel to the 2009 strategy game LEGO Battles is in the works and should reach DS gamers this spring.

Developed by Hellbent Games and produced by TT Games, LEGO Battles: Ninjago allows gamers to choose whether they want to play the "good" or "bad" single player campaign or take part in some multiplayer showdowns. Featuring familiar challenges from the original LEGO Battles as well as new ones, this new strategy game will require players to customise their armies before deploying them in missions.

Warner Bros. Interactive Entertainment and TT Games are unleashing an epic family friendly adventure with LEGO® Battles: Ninjago for Nintendo DS™, the follow-up title to the highly-successful LEGO® Battles videogame. Scheduled for release in Spring 2011, the game complements the line-up of LEGO Ninjago products to be released starting today and going throughout 2011.

Produced by critically acclaimed TT Games and developed by Hellbent Games, LEGO Battles: Ninjago allows players to become a master of Spinjitzu, an art form in which characters spin and become tornadoes to defeat their enemies, as they restore harmony to the world. Players can choose to play both “good” and “evil” single-player campaigns, test their skills in a variety of Battle Mode challenges, or play with family and friends in exciting multiplayer showdowns.

“LEGO Battles: Ninjago offers players a humorous way to immerse themselves further in the LEGO Ninjago toy line with action packed battles,” said Tom Stone, Managing Director, TT Games Publishing. “It is great to build upon the success of the first LEGO Battles game and expand the LEGO Ninjago world with new and classic LEGO characters.”

In LEGO Battles: Ninjago, gamers must recover powerful Ninja weapons and overcome challenges featuring dragons, larger-than-life battles and an exciting story line that includes cameos by fan favourites from LEGO Battles. Packed with action and fun, the game allows players to build and customize their own army of Spinjitzu heroes or Skulkin villains as they deploy armies on missions to defeat the enemy.

LEGO Battles: Ninjago features enhanced graphics and effects, four new multiplayer challenges, and two of the original multiplayer challenges from LEGO Battles, all of which offer kids and families hours of gameplay.

In a companion release today, The LEGO Group announced the launch of the LEGO Ninjago construction sets, as well as a new Ninjago world within the LEGO Universe MMOG.
