Family Guy: Back to the Multiverse is a 2012 video game based on the animated sitcom, Family Guy. It is a sequel of sorts to the Road to the Multiverse episode of the TV show. In this video game, a Bertram from an alternate dimension where Stewie didnt kill him arrives in the main Family Guy timeline, out on a mission to destroy any timeline where he doesnt exist. He builds a multiverse-traveling remote control and goes into another universe as part of his plan to lure Stewie into his trap. When Stewie and Brian decide to go find Bertram and kill him, Bertram hires henchmen to kill Stewie and Brian. A couple of these henchmen are characters from the Family Guy TV show, such as Ernie the Giant Chicken, Long John Peter, and Santa's work-overwhelmed elves. Stewie and Brian follow Bertram through 10 different universes, including an Evil Counterpart universe, the origin realm of Evil Stewie, a universe where progress has been frozen in the Golden Age of Piracy, and a universe ruled by the Giant Chickens.
This game provides examples of the following tropes:
Action Bomb: The North Pole level has elves with bags full of explosives, and explosive dolls.
Defeat Equals Friendship: In a sense. The head of Crippletron, the third boss of the game, is Joe Swanson. Joe is also an assist item in the game, which can be bought before this fight, but is not found within any actual levels until after you defeat Crippletron.
Even Evil Has Standards: Brian is pretty willing to gun down just about everyone that comes in their path and has a disgusting sense of humor (such as ignoring a wounded Joe Swanson crying for help after the Crippletron fight). But he calls Stewie a sick person after the latter kills Santa Claus by dropping a TV on him. Stewie naturally just insults him.
Hoist by His Own Petard: Bertram rides a T-Rex during his boss fight, which ends up eating him after he's been defeated.
Humongous Mecha: One serves as the second boss. Also, there's Crippletron returning from the show in the handicapped universe.
Late Arrival Spoiler: Those who haven't watched the episode "The Big Bang Theory" may be confused by how the Betram ingame is an alternate version.
Lightning Bruiser: Brian's guns shoot rather quickly as well as hits hard, his Alcohol makes his attacks stronger. Stewie's weapons are powerful and his Energy Drink increases his firing rate and reload rate.
Tag Team: Brian and Stewie are one in the story mode.
Talk Like a Pirate: Naturally in the Long John Peter level, including a rehash of Peter's shin gag with "Argh" in place of the usual wince.
Tempting Fate: Ironically, it's Death that does it. In the level where you assassinate Mayor McCheese, Death can be found lounging on a rooftop saying things like "boy am I glad no one's going to die today!"
This Is Gonna Suck: Stewie and Brian regularly brace themselves for a rough time whenever enemy-spawning vehicles or buildings arrive.
Unique Enemy: Early in the North Pole level, there is an "Employee of the Month" style picture of an elf who is wearing a red outfit, instead of the standard green outfit that every other elf wears. Later on, you actually see this elf, and killing him prompts Stewie to make a comment about him.
Verbal Tic: Stewie and Brian continuously pepper their dialogue with the insult "dick" in this manner.
Visual Pun: One of the pirate ships to be destroyed during the Long John Peter level has a mast featuring a parody of the FBI anti-piracy logo.
Weak, but Skilled/Unskilled, but Strong: Brian's weapons do less than damage than Stewie's but they have better accuracy to compensate. Conversely, Stewie's weapons have less accuracy than Brian's but make up for being more powerful.
We Can Rule Together: Bertram unsuccessfully tries to do this to Stewie right before he is eaten by his T-Rex.
