In addition to the minifigures, players can also build models of vehicles, such as the Batmobile, TARDIS, Mystery Machine or DeLorean, and put them into the game for characters to drive.

Each adventure world also contains a red brick for players to retrieve; these will unlock special bonuses, such as visual modifiers for characters or extra assistance at finding collectible items.

Unlike series such as Skylanders, Disney Infinity and Amiibo, the minifigures, vehicles and the USB toy pad are all made from real Lego pieces and can be freely built and customized.

The game's second year of content also introduced competitive multiplayer in the form of the Battle Arenas, allowing up to four players to compete in modes such as Capture the Flag.

Packs from the game's second year (September 2016–17) also unlock Adventure World Battle Arenas, competitive four-person multiplayer areas themed after each figure's respective franchise.

[11] Unlike other toys-to-life series such as Skylanders and Disney Infinity, Lego Dimensions allows all figures to be compatible with the existing title, rather than releasing a sequel.

[12][13] Arriving on Foundation Prime, a shapeshifting planet located in the center of the Lego multiverse, Lord Vortech (Gary Oldman), a being who has the power to shapeshift and travel through dimensions, and his robot minion X-PO (Joel McHale) seek the twelve Foundation Elements, the cornerstones of time and space itself, in a bid to merge all the dimensions into one under Vortech's control.

Unfortunately for Vortech, his own body cannot handle too many more dimensional jumps, forcing him to open vortexes to the different dimensions and recruits their villains to help him search for the elements while imprisoning the heroes pulled through them.

When Robin (Scott Menville), Frodo Baggins (Elijah Wood), and MetalBeard (Nick Offerman) are pulled into the vortexes, each unknowingly in possession of one of the elements, Batman (Troy Baker), Gandalf the Grey (Tom Kane), and Wyldstyle (Elizabeth Banks) all jump in after them.

Along their journey, they meet and assist the various heroes of the dimensions they visit, such as Dorothy Gale (Laura Bailey), Homer Simpson (Dan Castellaneta), Dr. Emmett Brown (Christopher Lloyd), Wheatley (Stephen Merchant), and Scooby-Doo (Frank Welker) while fighting numerous villains, including the Wicked Witch of the West (Courtenay Taylor), Lord Business (Nolan North), The Joker (Christopher Corey Smith), Master Chen (William Salyers), Saruman the White (Roger L. Jackson), Lex Luthor (Travis Willingham), the Daleks and Cybermen (Nicholas Briggs), Two-Face (Baker), Sauron (Steve Blum), the Digital Overlord (Baker), Brainiac (Dee Bradley Baker), The Riddler (Roger Craig Smith), General Zod (North), as well as Vortech himself twice.

He merges Robin, Frodo, MetalBeard, and a piece of himself into a giant mutant known as the Tri, (Menville, Wood, and Offerman) and sends it to wreak havoc on the trio's home dimensions.

In a post-credits scene, an unknown figure finds a piece of Vortech's body, the same one that had miraculous survived the Tri's vanquishment, in the remains of Foundation Prime's palace.

[14][15][16] IGN awarded it a score of 7.7 out of 10, saying "Lego Dimensions' great characters and fun references consistently left me with a big dumb grin on my face.

Their summation was that it was "poor value", stating that the last few Lego games were "pretty much as good as this one, but players can play as their extensive character rosters without having to buy expensive expansions.
