Lego Battles invites players to build their own armies to take part in solo campaigns and online multiplayer contests. The titles, to be developed by Hellbent Games, will be based on the themes Lego Pirates, Lego Castle and Lego Space.
"Lego Battles offers players the action-packed and humour-filled gameplay that make Lego games great, along with the added bonus of linked multiplayer battles on DS," said TT Games MD Tom Stone.
"We are excited to introduce a new Lego video game experience to fans and young gamers and look forward to expanding upon the beloved toy lines."
TT Games has previously given Star Wars, Indiana Jones and Batman the Lego treatment to critical acclaim and commercial success.
