Dreamtime

Set in the Australian Aboriginal Dreamtime, this CORPS supplement does a respectable job in tackling a difficult roleplaying genre. You need either the main rulebook, CORPS, or the free "Nutshell" version of CORPS in order to play. The game is deliberatly vague as to whether the player characters are actually human or perhaps "others" who walked the earth before the people came. Or perhaps both, depending on which world they happen to be in at the time.
