Ninjago is about ninjas who practice "Spinjitzu," the art of spinning into a human tornado like the Tasmanian Devil, and a martial art that doesn't sound like it lends itself to strategy. In "good" or "evil" single-player scenarios, you can play out the battles between the ninjas and the "Skulkin" skeleton army. There are also multiplayer modes, including "four new multiplayer challenges, and two of the original multiplayer challenges from Lego Battles." Ninjago will be released on DS this spring. In addition, a Ninjago-themed world is being added to the MMO Lego Universe.
