in any area linked to the one from which the attack was made. If there is already a rocket there, the second rocket may be added to the first to make a two-stage rocket. There is no limit to how large a rocket can be. The rocket's range is dependent on the number of stages, so a one-stage rocket can hit all adjacent areas, a two-stage rocket can hit any areas two away, and so on. When a rocket hits an area, it destroys all armies in the area and renders it radioactive, making it impassable to all armies. In addition, armies in all the adjacent areas are also removed from the board, and any missiles in those areas go off. This may lead to a chain reaction as nuclear explosions detonate missiles in adjacent areas, which then detonate further missiles. If there is a missile in an area that is successfully occupied, then the occupier is now the new owner of the missile. Areas that are irradiated can be cleaned up as long as the reclaiming player takes no other actions that turn. Victory conditions Play continues until there is only one player left. If all armies are eliminated by a nuclear chain reaction, the game ends in a stalemate. Publication history In 1974, Mike Hayes, a student at University of Sheffield, self-published a game of nuclear war in Europe for 2–7 players packaged in a plain red box titled The Warlord. Hayes republished the game in 1978 in a blue box. In 1980, Games Workshop acquired the rights from Hayes and revised the game, simplifying the rules, reducing the number of players to 4, removing hydrogen bombs, allowing irradiated areas to be cleaned up, and cutting the board map in half (eliminating Eastern Europe). This revised game was released as Apocalypse: The Game of Nuclear Devastation with cover art by Tony Roberts. (The cover art had been used three years previously on the cover of the Orbit/Futura paperback edition of Jerry Pournelle's science fiction novel The Mercenary.) After Apocalypse went out of print, Mike Hayes reacquired the rights and republished his full original game, retitled Classic Warlord, in 2012. Computer game A computer game version, Apocalypse: The Game of Nuclear Devastation, was published by Red Shift under license from Games Workshop in 1983 for the ZX Spectrum and BBC Micro.
