Up will feature playable versions of all four characters from the movie--Carl, Russell, Dug the lovable dog or Kevin the prehistoric bird--possibly making this the first game allowing players to take control of an old man with a walker. The action-adventure game also offers two-player co-op, and a four-player multiplayer aerial combat mode.

Strangely enough, the announcement was conveniently accompanied by a demo release. Check out the PC demo on FileShack.
