The game will star Batman fighting crime in Gotham City.

An early build for the PS2 console was shown at certain conferences (such as at Game On in London) by designer Jonathan Smith, with a small playable area sporting the exact same HUD as Lego Star Wars II.

Characters on screen each have individual animations and both Batman and Robin have their original TV show dressing style. There will 36 levels in the game (18 heroes and 18 villains).

After you play through the level from the heroes' perspective you will unlock the level from the villains' perspective.

A harbor level has been shown in a screenshot, featuring vilains Killer Croc, The Scarecrow, and Catwoman. A similar grappling system to the one used in Lego Star Wars II will be used. The style of the game will focus more on the original TV series and comics rather than the new movies. The Joker, The Penguin, and Harley Quinn will be playable characters.

Developer Jonathan Smith stated that the company will be developing more Lego games in the future. He did not offer any names.
