Pac-Man 2: The New Adventures is a graphic adventure game, a vast departure from its predecessors. Players assume the role of Pac-Man as he must carry out different quests given to him by other characters. Many of these involve retrieving a specific item, such as a bottle of milk or a flower. Unlike other adventure games, players cannot control Pac-Man directly, who will wander and interact with the in-game world at his own pace.[2] Instead, players use a slingshot to guide, or "influence" Pac-Man to his destination or to attract his attention towards a specific object. The player is able to also use the slingshot on Pac-Man, which can result in various changes to Pac-Man's current mood, or can wake him up after fainting.
In each quest, the player will need to solve puzzles to progress. The solutions to these puzzles are based on Pac-Man's moods, which differ based on the player's actions. For example, the player can shoot down an apple from a tree, which Pac-Man will eat and makes him happier, while shooting Pac-Man in the face will make him irritated or depressed. Pac-Man's moods will also determine how cooperative he becomes; for instance, making Pac-Man too happy will cause him to become smug and cocky, and as a result less willing to follow the orders of the player. Some sections of the game follow Pac-Man riding on a hang glider or in a minecart through "chase" scenes, which require fast-reflexes from the player. Pac-Man may sometimes encounter his enemies Blinky, Pinky, Inky, and Clyde, where he will immediately become frightened and run around the screen. Feeding Pac-Man a Power Pellet, stored in an inventory at the bottom corner of the screen, will transform him into Super Pac-Man; giving him the ability to fly at high speeds and eat the ghosts. If the player visits an arcade, they can play the original Pac-Man. Finding three game cartridges across locations in the game will allow them to play Ms. Pac-Man in the SNES version; or a new original game, titled Pac-Jr. in the Sega Genesis version.
