Family Guy: Back to the Multiverse is a humorous TPP action game created for fans of the popular animated series of the same title. The game draws inspiration from the episode "Road to the Multiverse" and takes players to alternative worlds full of references to the series.

In the game, we play as Stewie and Brian, who must stop Bertram - Stewie's evil half-brother from an alternate dimension. Bertram wants to conquer the multiverse, using an army composed of characters known from the series, such as Chicken Ernie, Evil Stewie and Long John Peter. Players travel through seven different worlds, where they face unusual opponents, from the Amish building futuristic weapons to pirates and giant chickens from outer space. Each world offers a unique style and humor referring to the character of the series.

The gameplay is a typical action game, with players battling hordes of enemies using a variety of weapons, from swords to futuristic laser cannons. The single-player campaign lets you take on the role of Stewie or Brian, and the entire story is presented in the style of an episode of the series, with animated scenes and characters from the original cast.

Family Guy: Back to the Multiverse also offers co-op and multiplayer modes, but they are limited to local multiplayer with no online play. The co-op maps are smaller versions of the campaign levels, and the challenges themselves are much simpler than in other games of the genre.
