Pac-Man 2: The New Adventures, known in Japan as Hello! Pac-Man (ハロー! パックマン), is a side-scrolling game incorporating both puzzle and action-adventure elements. It was produced and published by Namco for the Super Nintendo Entertainment System (SNES) and Mega Drive/Genesis systems, and was released on April 6, 1994 by Namco. It is based loosely on previous games in the Pac-Man series (mostly Pac-Land), and also appears to contain certain elements from the animated series. However, its gameplay differs greatly from the maze games that comprise the majority of the games in the series.

In Pac-Man 2, the player plays the role of an observer and assistant that follows Pac-Man as he sets out to accomplish various tasks. Pac-Man himself walks around in a cartoon world and interacts directly with the player, as well as with objects and other characters. The player cannot control Pac-Man directly, but instead can direct his attention in various directions, and is armed with a slingshot that can be used to strike certain objects, including Pac-Man himself.

Pac-Man's mood varies throughout the game, usually in response to his environment or the player's actions, and generally his mood affects his actions and his willingness to cooperate with the player; the varieties of "bad" moods can at time compromise the player's ability to progress. There are a few instances, however, where Pac Man is required to be angry. Hitting objects with the slingshot can often get Pac-Man to look at that object and piece together parts of the puzzle he is currently trying to solve.

Throughout the game, Pac-Man is occasionally harassed by three of the four ghosts from the classic Pac-Man games. When this happens, Pac-Man is paralyzed by fear and eventually faints, unless the player gives him a power pellet. Then Pac-Man becomes Super Pac-Man for a brief time and flies around, eating the ghosts. In some cases, the ghosts may leave behind important objects.
