Colossal Adventure

No, "Colossal Adventure" is Level 9 Computing's 1983 adaptation of the original "Colossal Cave Adventure" created by Will Crowther and Don Woods in the 1970s. Level 9 expanded the game with additional locations, puzzles, and treasures beyond the original mainframe version. It was designed to bring the Adventure experience to British home computers that could not run the original PDP-10 mainframe game.

"Colossal Adventure" was released for a wide range of 1980s British home computers, including the ZX Spectrum, BBC Micro, Acorn Electron, Commodore 64, and Amstrad CPC. Level 9 Computing was known for developing games in a portable format that allowed them to target many 8-bit platforms. This broad availability was key to the company's commercial success in the UK.

"Colossal Adventure" was developed by Level 9 Computing, a British software company founded by the three Austin brothers—Pete, Mike, and Nick Austin—in 1982. Level 9 became one of the most prominent British text adventure developers, creating the "Middle Earth" trilogy (beginning with "Colossal Adventure") and the "Silicon Dreams" trilogy. The company was based in High Wycombe, England.

Level 9 expanded the game world significantly, adding new locations, puzzles, and treasures beyond the original Crowther and Woods version while retaining the cave-exploration structure and fantasy elements like the dragon and pirate. Level 9 also implemented their own text parser and data compression technology to fit the expanded game into the limited memory of 8-bit home computers. The result was a substantially larger adventure than the original.
