LEGO Batman is an unauthorized platformer that is based on the J2ME version of LEGO Batman: The Mobile Game which was released in 2008. BMB published LEGO Batman in Russia for the Sega Mega Drive in 2014. Additionally, the game was developed on the same engine as Ben 10, Mario 4: Space Odyssey, and a number of other games.
It feels very much like playing LEGO Batman: The Mobile Game, which is a good thing. The player assumes the role of Batman, and the goal of the game is to gather as many gears as possible. The adversaries include Goons of the Riddler, Criminals, and Santa Goons. In addition to studs, the game also includes blank cards, which were most likely generated randomly. If you gather 200 of these, you will gain an additional life. They also have the potential to acquire additional lives, which are represented by batman symbols. Strangely, the player is tasked with rescuing Santa Claus at the end of the game. Unfortunately, there is no further information available.
