Pack-Man: five joysticks as one

A modified version of Pac-Man that lets five people take control over the pill eating phasmophobic, Pack-Man is another example (for more: 1, 2) of a single-player game modded to let more than one person play. Using five custom-built joysticks, the creators used "MIDI cables to communicate with a microcontroller, which then sends information on to a computer that's running the original Puck Man ROM". What this adaptation means is that Pac-Man will only change direction if the users have democratically chosen to do so.

Usually the game runs at 10% of the game's normal speed to compensate for the additional time needed to co-ordinate the group, but every 8 minutes the game reverts to normal speed causing havoc and inevitable death for poor, democratic Mr. Pac-Man. Be sure to check out the MP3 recording of a group of players reacting to this unexpected speed up.
