Pac-Man Plus is an arcade game released by Bally Midway in 1982, and it is the 4th title in the Pac-Man series of games. Like Ms. Pac-Man, this update to the original game was created without Namco's authorization.
Pac-Man Plus has the same basic goal of all of the early Pac-Man games: eat all of the Pac-Dots and Power Pellets before Pac-Man is caught by the ghosts. Just like the other early Pac-Man games, Power Pellets can be eaten so that the ghosts will become vulnerable and turn blue for a short length of time. Despite advertising stating that Pac-Man Plus was "Exciting!" and "New!" this game is actually just a modifier chip for the original Pac-Man, and the gameplay is essentially identical to it, with only minor gameplay tweaks and altered graphics (notably, the maze is green, compared to the original blue, the ghosts are slightly cross-eyed, the fruits have been replaced by alternative objects, including a can of cola). The most significant changes in the gameplay, however, is that eating a bonus fruit causes the ghosts to become vulnerable and invisible, doubling the score for eating them; and that eating Power Pellets would often have unpredictable effects (such as turning only three ghosts blue or turning the maze invisible).Because there were so few differences between Pac-Man and Pac-Man Plus and because the game was released right before the video game crash of 1983, Pac-Man Plus was never ported to home video game systems or computers. However, there have been efforts by some homebrew game developers to port Pac-Man Plus to classic game consoles such as the Atari 2600, and more recently the Atari 5200 and the Atari 7800. In addition, Jakks Pacific released a new Pac-Man TV Games collection that featured Pac-Man, Pac-Man Plus, Super Pac-Man, and Pac & Pal. It is featured on the Plug n' Play games Pac-Man Gold Edition, Retro Arcade Featuring Pac-Man and Super Pac-Man Collection.
