Family Guy: Back to the Multiverse is an action-adventure third-person shooter video game developed by Heavy Iron Studios and published by Activision. The game is based on the American animated television series Family Guy, most notably the episode "Road to the Multiverse", and was also a continuation of the episode "The Big Bang Theory". It also featured the return of Stewie's evil half-brother Bertram, who was killed in the show. The game was released in North America on November 20, 2012, in Australia on November 21, 2012, and in Europe on November 23, 2012, for Microsoft Windows, PlayStation 3, and Xbox 360. It was the first Family Guy console game since Family Guy Video Game! in 2006. Upon release, Family Guy: Back to the Multiverse received negative reviews. While praise fell towards its humor, characters, and return of the original cast, the game was criticized for its gameplay, graphics, and story. When the game was available for pre-order, people who pre-ordered the game received a special level, based on Aliens: Colonial Marines, another video game based on the Aliens trademark also owned by 20th Century Fox, which was released the next February to similar negative reception. In December 2014, Family Guy: Back to the Multiverse was removed from Steam. Gameplay Players control Stewie Griffin and Brian Griffin in an adventure that pitted them against Stewie's evil half-brother, Bertram. Back to the Multiverse featured both co-operative and competitive multiplayer modes built around the characters. Extra challenge levels, multiplayer maps, costumes, and playable Family Guy characters were unlocked through gameplay. Plot Brian and Stewie are spending time at home when Bertram appears out of nowhere in a flash of light. Stewie is appalled by this, as he had killed Bertram in the past. Bertram responds by explaining that he is from another reality where Stewie never killed him, and expresses his disgust that there exists a universe without him in it. Bertram then exclaims that because of this, he will build an army from all the depths of the Multiverse, and use it destroy Stewie's universe entirely. After Bertram uses his remote to travel out of their realm, Stewie takes out his own Multiverse remote and declares that he and Brian will stop Bertram at all costs. They then travel out of their world and try to track Bertram down, but are forced to encounter his army along the way. Some members
