Heroes Unlimited is a superhero role-playing game written by Kevin Siembieda and first published by Palladium Books in 1984. The game is based upon the Palladium Books Megaversal system and is compatible with other games that use the Palladium system.
Heroes Unlimited features superheroes fighting supervillains in a comic book-like world. The game's introduction states that the game was designed to be a "thinking man's" superhero role-playing game where the characters were vulnerable and could not amass an incredible number of skills or abilities. The experience point-system of the game allowed users to defeat one's enemies with heroic sacrifice. Characters in the game are defined by "the eight attributes," skills (dependent on education level), and class, which allows the selection of certain powers or enhanced skills or equipment. The classes include super-powered beings to aliens to technology-based or special-training-based characters. Some classes and super-powers (such as the ancient master class or invulnerability powers) start powerful but do not mature, while other classes and powers have effects strongly tied to character level.
The second edition of the game added updates to the previous supplements, in addition to the new play options, along with several new supplements produced by Palladium Books. This edition added new powers and minor rule changes which allowed users to expand play options by adding superpowers to classes, the introduction of the "crazy" heroes option, and added magic-powered characters to the game at the request of the players. The revised edition also included a short rules summary of the Palladium game Teenage Mutant Ninja Turtles & Other Strangeness, adding mutant animal character rules and a shortened selection of animals for character creation. The mutant animal characters are generally weaker than standard heroes as the TMNT supplement Turtles Go Hollywood noted.
Heroes Unlimited was first published by Palladium Books in 1984 and revised in 1987. A second edition was published in 1998.
William A. Barton reviewed Heroes Unlimited in Space Gamer No. 72. Barton commented that "if you desire hero-types like Batman, Captain America, Robotman, or Wolverine, Heroes Unlimited is a superbuy, even if you use it as nothing more than a sourcebook for an existing game."
Heroes Unlimited was ranked 40th in the 1996 reader poll of Arcane magazine to determine the 50 most popular roleplaying games of all time. The UK magazine's editor Paul Pettengale commented: "Superhero roleplaying for the Palladium player, but not all that easy to pick up."
