The original Colossal Cave Adventure was the work of Will Crowther and was released in 1976. In fact, it paved the way for the now classic Zork, Rogue and also for the Williams-owned Mystery House.
In recent years they had retired from the video game industry, but boredom due to the lockdown led them to start developing Colossal Cave 3D Adventure.
“I was looking for something interesting to program until Roberta suggested Colossal Cave,” said Ken Williams. “Roberta started the 3D port and I built a team. The deeper we got into the game, the more layers of complexity we discovered, which explain why it became an industry phenomenon. It has elements of action, humor, adventure, interesting characters, scoring system and a huge world to explore. The game is sure to please the new generation and is 100% different to what is out there right now,” added Williams.
