From GameWatcher: “Evil Genius was released in 2004 to positive reviews and is currently available for free for a limited time, courtesy of UK studio Rebellion as a promotion for the long awaited sequel due out later this year. In a twist to the usual giveaway format, Rebellion are not disclosing when this offer will end, so grab your copy quick to avoid disappointment.”
