Piranha was the name of a terrible
hack of
Pac-man. It was released in 1981 by "
GL" as it is quoted on the
attact mode screen. You played a
piranha trying to eat all of the dots in a free-form area (no walls to speak of), with the ghosts replaced by Octopi or some sort of squid monster. The
graphics and
sound are
terrible, and the play
control is
awful. The ghost logic seems to still be used to having
walls, so they make some poor decisions when trying to hunt you down. All in all, not a very good hack.
An insane rarity (if it even still exists) in
arcades, this hack is playable in
MAME with the standard pacman
driver.
