Rifts Chaos Earth

Rifts Chaos Earth is a post-apocalyptic role-playing game from Palladium Books. It is a spinoff and prequel to their popular game "Rifts", which uses a similar form of Palladium's Megaversal system.
History.
In the early 2000, Palladium was experiencing a downward trend, so to try to offset decreasing sales, Palladium continued creating new settings; as a result the brand new game "Rifts Chaos Earth" (2003), a prequel to "Rifts", was released and soon supplemented by a few sourcebooks (2003).
Description.
"Chaos Earth" was originally intended to be a parallel dimension to "Rifts" where the massive deaths were caused a minute after midnight when the released Potential Psychic Energy (P.P.E.) was magnified. Everything that happened in "Rifts" happened on a smaller scale in "Chaos Earth". In "Chaos Earth", most of humanity survives and has to fend off the supernatural. This game style can be played in Palladium's "Nightbane" series. Sometime after its original press description in an early "Rifter", the game changed from a parallel dimension to "Rifts" history, perhaps due to the level of interest in Rifts' past. Now in the Palladium Megaverse, the "Chaos Earth" setting is the period in Earth during which the rips in space-time known as rifts ripped apart mankind.
"Chaos Earth" gives players a chance to play in a world somewhat more recognizable than the world of "Rifts". Monsters are only starting to appear and there the forces of humanity are still trying to hold on to the civilized world that Earth had been, as opposed to "Rifts" where characters live in a world where violence and horror have been commonplace for centuries.
