Up

Up follows the storyline of the film, featuring Carl, Russell, and Dug walking through the jungles of Venezuela. All of the mentioned characters are playable in the game, and in all versions, the player must switch between them to take advantage of their unique abilities to overcome obstacles, while being careful to avoid injury as all playable characters (depending on the version) share a single health bar.

The PlayStation 3 version of the game was the first game based on a Pixar film to support the trophy system. This version and the Xbox 360 version feature online achievements themed after Wilderness Explorer badges. All versions feature multiplayer aerial combat in addition to the main story mode.

The story centers on an elderly widower named Carl Fredricksen and an earnest young Wilderness Explorer named Russell who fly to South America in a house suspended by helium balloons.

The PlayStation 3, Wii and Xbox 360 versions of the game follow the film's plot more tightly, spanning eleven levels, with some liberties taken. The Microsoft Windows, Mac OS X, PlayStation 2 and PlayStation Portable versions of the game are a looser adaptation, in which Carl and Russell take detours through the jungle. Consequently, these versions of the game have over 20 levels.

The PlayStation 3, Wii, and Xbox 360 versions received "mixed or average" reviews according to the review aggregator Metacritic. In Japan, where the game was published by E Frontier exclusively on Nintendo platforms on December 3, 2009, Famitsu gave it a score of all four sixes for the DS version, and three sevens and one six for the Wii version.
