GameSpot News has learned that a sequel to Evolution is already in the works for the Dreamcast. Sources inside Sting (the game's developer) have revealed several details about the game as well. Evolution 2 will feature the same characters as the original title but the story will take place a half year from where the first game left off. Also, this time around all of the dungeons (except for one) will not be random.
Evolution 2 currently carries no release date, but it has been rumored that it will come out before year's end in Japan.
