Family Guy: Back To The Multiverse was planned for Wii/3DS, but was cancelled
Activision and developer Heavy Iron Studios were once working on Family Guy: Back To The Multiverse for both Wii and 3DS. These two versions would have been very different, as they would have featured an isometric perspective.
Unseen 64 shares the following information:
The Wii version of the game was being designed around the Wii remote and nunchuck, although did not make use of any of its unique features, such as the motion sensors or pointer. It was planned to be almost entirely identical to the 3DS version in terms of gameplay.
Whereas the shooting mechanics in the released HD title used a manually controlled reticule, the 3DS and Wii game used what one developer described to us as an “auto targeting system” instead, given the isometric camera view. This automatically locked on to potential targets within the immediate area to fire at with Stewie’s laser gun or Brian’s pistol.
According to one of the programmers on the Multiverse project we spoke to, the 3DS and Wii version were outlined to be otherwise “completely undifferentiated” in terms of story; even featuring the same dialogue and voice acting clips. It would have also included the two main playable characters of Brian and Stewie Griffin from the other version.
Ultimately, Activision canned the Wii and 3DS versions of Family Guy: Back To The Multiverse back in August 2011. Playable prototype builds were ready at the time.
