LEGO Minifigures Online (LMO) is a third person multi-player action adventure game in which the player fights and collects Minifigure characters through a number of different worlds, starting from the Pirate World, then going through the Medieval Kingdom, Mythology, Space and Dinosaur worlds.
Each Minifigure has two unique powers and can be upgraded to become stronger, faster at running or building elements. The game is designed to allow the player to use three different characters at the same time, switching from one to the others depending of the needs of the moment.
The video game is tied with real merchandising: If you buy a real Minifigure bag in a shop, you will find a code that can be used to unlock the very same character in the game.
Gameplay wise it could be put together with Diablo and Torchlight in the family of hack and slash games, but without any bloody violence due to the age rating.
