The dawn of time...You are one of the first creatures to inhabit the earth! There were no peace treaties back in the early days, just your character in a jaw-clamping, teeth-flying, survival of the fittest, right to live. With the new Multi-change option and "Book of Life" feature, you can create and save up to 50 of the biggest, baddest creatures you can conjure up! The only thing standing between you and the fabled land of Eden, are 4.6 billion years worth of Mother Nature's meanest creations!
