Nick and Alex enlist the help of the game's programmer and head to the video arcade for a final showdown with "Arcade" and his deadly virtual world. While Alex is able to release her friends from a virtual prison, she also ended up freeing the evil little boy, who taunts Alex in the final moments of the film.
In the original CGI version, however, the film ends on a somewhat happier note, with Alex, her friends, and Albert (the programmer) simply walking away from Dante's Inferno, with the donor's soul seemingly laid to rest.
