Lego Battles: Ninjago (also known as Lego Ninjago: The Videogame) is a video game published on 12 April 2011 in North America and April 15, 2011 in PAL territories for the Nintendo DS and is a follow-up to Lego Battles video game. Both games were developed by Hellbent Games and co-published by WB Games and TT Games Publishing. Unlike the previous game, this game is loosely based on the pilot season of Ninjago: Masters of Spinjitzu.
The game is a sort of mixture between normal Lego video games and the Battles series. Players control six builders and seven heroes. Each hero has three versions, two of which must be researched. In these modes, two special abilities ("spells") can be used. Teams can also build five different buildings: the keep, the headquarters of the team, the brick bank, where builders can drop off bricks, the mine, which automatically produces bricks, the barracks, which produces heroes, and the tower, which fires projectiles. In addition, towers can have upgrades based on elements. The Ninjago story is based on the ninja training and their quest to find the four golden weapons in the underworld. The skeleton story is based on the skeleton army (led by Samukai) searching for the golden weapons. The story is based on the Ninjago: Masters of Spinjitzu pilot episode (but with some minor differences). Some characters in the game are from different Lego themes; Agents, Mars Mission etc.
