This superset of the original Adventure was first released in March 2003. It incorporates my Adv660 expansion of the game. See Adv770 FAQ (06 July 2025) for answers to some questions about the game. (I said a FAQ! – not a walkthrough or a hint sheet.) There is also a separate bug list (26 July 2026), which lists known bugs and records their fixing.

Play it now

The current A-code version, used to construct all builds on offer, automatically gives the game a persistent state. This means that if the game is interrupted in whatever way, on restarting it will automatically restart at the point of interruption, unless a new game is explicitly requested.

Pre-built versions

Thanks to the magic of Emscripten, there is now a pure HTML/Javascript version which should run locally on your machine in any robust modern browser. You can either kick it off straight away via adv770.html (1.9 MB) and then save the page at any stage, or you can download the zipped version , unzip it and point your browser at the resulting adv770.html file.

A unified Linux console/browser build with command editing, defaulting to browser-based display. Console mode can be forced by adding -C to command line invocation. See the bundled README file for more details.

Game sources

A-code source of Adv770 can be found in the gzipped tarball adv770-2.33-src.tgz (2.2 MB), or equivalently in the zipfile adv770-2.33-src.zip (3.5 MB).

Both packages also contain sources of the acdc A-code to C translator and of the A-code kernel, used in building executables offered by this page. They also contain game's C-soures, already converted frome the A-code source by the acdc translator and combined with the required kernel sources, ready to be compiled and linked with any ANSI C compiler. Full A-code documentation (version 0.9) and other potentially useful bits and bobs are also included.
