LEGO Dimensions is a cross-platform game by Traveller's Tales and published by Warner Bros. Interactive Entertainment (WBIE).
The Starter Pack consists of the game itself and a Toy Pad (both platform-specific), along with LEGO models of Characters from three different franchises: Lord of the Rings (Gandalf), The Lego Movie (Wyldstyle), and DC Comics (Batman), and a Vehicle (Batmobile).
By placing a combination of the models on the Toy Pad, the depicted Character, Vehicle or Gadget (e.g. the Ghostbusters Ghost Trap) appears on-screen in the game. Each Character, Vehicle or Gadget has a variety of different abilities which are used to solve puzzles and progress through the story.
A character from a particular franchise also allows access to the open-world Adventure World associated with that franchise.
Although the story can be completed with the Characters and Vehicle provided in the Starter Pack, the player cannot obtain all the hidden collectables without using the abilities of models not included. Also there are many Adventure Worlds which cannot be accessed by the Characters in the Starter Pack.
Additional models are available in four different types of Pack. Each Pack contains models from a single franchise.
Fun Packs contain two models - a Character and a Vehicle or Gadget. They allow access to the applicable franchise Adventure World.
Team Packs contain four models - two Characters, a Vehicle and a Gadget. They allow access to the applicable franchise Adventure World.
Level Packs contain three models - a Character, a Vehicle and a Gadget. They allow access to the applicable franchise Adventure World, and also provide a complete new Story Level.
Story Packs contain three or more models of various types, and also a new theme for the Toy Pad. They allow access to the applicable franchise Adventure World and also provide multiple new linked Story Levels, relating to the franchise.
Finally a number of single Character Polybags have been released as special offers or in association with particular events.
