LEGO Dimensions is a toys-to-life video game developed by Traveller's Tales and published by Warner Bros. Interactive Entertainment released in September 2015. It features worlds and characters from many different franchises, including two levels based on Portal 2 - one in the base game (which makes reference to Half-Life by mentioning Black Mesa) and an extra level that can be unlocked by purchasing the related Level Pack. The Level Pack includes a Chell minifigure, a Companion Cube that can be upgraded to deflect lasers and refill player health, and a Sentry Turret that can be upgraded to fly, as well as fire missiles and lasers.



In the center of the Lego Multiverse, Lord Vortech and his robotic minion X-P0 find a world called Foundation Prime, which Vortech has spent years in search of. This world contains leads and hints for finding the Foundation Elements, the cornerstones of time and space itself scattered across the dimensions long ago, which Vortech seeks in a attempt to merge all the universes into one under his control. When X-P0 voices his dissent, he is banished to the world of Vorton. Unfortunately, Vortech's own body cannot handle too many more dimension jumps, forcing him to open vortexes to many different worlds, recruiting villains to aid in his search for the Elements.

Meanwhile, in the DC, Lord of the Rings, and The LEGO Movie universes, Robin, Frodo, and Metalbeard each unknowingly hold one of the Elements, and are pulled into rifts created by Vortech. Batman, Gandalf, and Wyldstyle all jump in after them, leading them to each other before finally landing on Vorton. Aided by X-P0, the three use a portal-generating Gateway to travel through worlds within the multiverse to search for the five missing Keystones that give the Gateway unique powers, as well as the Foundation Elements, hoping to find their missing friends and stop Vortech's plan from succeeding.

GLaD To Meet You[]

The seventh stage of the game, "GLaD To Meet You," takes place in the Aperture Science Enrichment Center, after X-P0 tells the heroes that one of the Foundation Elements is a "delicious and moist cake," and that knowledge of it is seemingly programmed into all AI constructs. The trio of heroes enter the Enrichment Center and are greeted by GLaDOS, who they inform that they're in search of a cake. GLaDOS agrees, but first requests that they perform a series of tests. They use the power of the five different Keystones to complete the otherwise impossible tests, which GLaDOS calls "cheating." As they travel through the test chambers, Wheatley finds them, inadvertently leading them further into the chambers before they finally enter GLaDOS' room. She taunts them and battles them, and as they continue to best her, she grows more and more frustrated. Finally, she drops them into the Incinerator Room below, where they disable the incinerators and find the cake. She brings them back up and threatens them again, before they leave and GLaDOS asks, "Why must they always leave me?"

Riddle-Earth, The End is Tri, and The Final Dimension[]

GLaDOS and the Animal King turret show up in the eighth level, Riddle-Earth, with GLaDOS having converted a room in the Middle-Earth kingdom of Minas Tirith into a test chamber. In her words, if she cannot bring the heroes to the test chambers, she will instead bring the test chambers to them.

After the fourteenth level, The End Is Tri, the heroes travel across multiple universes in search of a way to stop Vortech for good. Remembering that GLaDOS had located them in Middle-Earth, they ask her for help, to which she responds, "Tell it to my morality core. Oh, that's right - it was removed and replaced with an amorality core instead." She then shows them the core to drive the point home, and Wyldstyle, taking advantage, proceeds to replace it with the Morality Core again before she can bring in a group of turrets to kill them. Batman makes a deal with her - they will only put the Amorality Core back once she agrees to help and returns with them to Vorton. Soon, the heroes bring the Doctor from Doctor Who along so that he can fix a broken X-P0, and GLaDOS claims to be the AI he's come to fix and that the problem is her Morality Core. (He immediately shoots this suggestion down.)

GLaDOS helps the heroes find a way to Foundation Prime, and uses a Rocket Sentry to help in the battle against Vortech, as well as helping create a device to help the heroes trap him in a rift loop. During the credits, GLaDOS reviews information on Chell and starts writing a message to her, in the form of a song called You Wouldn't Know. To her delight, the Amorality Core drops out of a portal.

Aperture Science[]

Chell is brought through a portal into Aperture Science, alongside Wheatley, who has been fitted with an anti-gravity module, allowing him to move freely. As the two continue, an elevator "breaks down" and Wheatley's antigravity fails after Chell tries to grab onto him, dropping them into the Test Shafts of Old Aperture. After escaping (and discovering a Core that Cave Johnson had imported his own mind into), they go through more tests before finally making it back to GLaDOS' chamber. She attempts to kill Chell with more neurotoxin, but a Core Transfer results in her being replaced with the Space Core. Afterwards, Chell and Wheatley enter a back room GLaDOS had been trying to hid, finding a large amount of Black Mesa boxes and a gateway similar to the one used by the heroes. Chell and Wheatley enter, leaving their fates unknown.


  • During the credits, GLaDOS sings a new song written by Jonathan Coulton, called "You Wouldn't Know." The song's message on the surface is about GLaDOS' new look at life after her morality core was replaced, though it could also be seen as sarcastic, such as the lines "I forgive you everything, you monster." It also seems to bring up her loneliness, such as in the line "I can think of reasons why you are never coming by for me."[1]
  • Chell is fully playable, included in the Level Pack A Portal 2 Adventure. This marks the first time in which the player can see her face without using a portal, as well as her facial expressions.
  • During her boss fight, GLaDOS is distracted by H.A.L. 9000 from 2001: A Space Odyssey; GLaDOS, not knowing who he is, asks if the Black Mesa Research Facility sent him.
  • Multiple characters have interactions with Chell, such as Doc Brown from Back to the Future admiring her portal gun, Superman comparing GLaDOS to Brainiac, or K.I.T.T. from Knight Rider asking her if she's had any bad experiences with AI in the past.
  • Chell's LEGO minifigure is based on her model, the visual design of which is based on voice actress Alésia Glidewell. Glidewell also appears as herself in the associated E3 trailer.[2]
  • In the final cutscene for the level pack, multiple boxes labeled Black Mesa can be seen.
  • The main game seems to have multiple contradictions - it's set after the events of Portal 2, as GLaDOS is still online and mentions Chell indirectly, though Wheatley is back in the facility and attached to his rail. However, in the level pack immediately afterwards, he appears through a portal and GLaDOS gets replaced with the Space Core.
