Finally, Miranda comes into play.
Note: According to
https://larryniven.net/reviews/other.shtml , a third game called "Ringworld - Within in ARM's Reach" was planned or being developed, but it was never released.
The game is a sequel to Tsunami's first adventure, Ringworld - Revenge of the Patriarch. Both games are based on the Ringworld novels by Larry Niven.
The story continues right after the vents of the first game. The heroes from the first game - Quinn, Miranda and the Kzin "Seeker of Vengeance", have destroyed the ship the Patriarch of the Kzin had sent to destroy the Fleet of Worlds of the Puppeteers. While they were able to leave Ringworld alive, the Patriarch has put a price on their head, so they see no other option as to go back to Ringworld in order to hide.
Unlike the first game, where you only played as Quinn, you control all three characters, and you can switch between them via menu.
