Chaos will work under at least Workbench 1.3 and Workbench 2.0 and should work on anything subsequent. It will, however, only work correctly on PAL systems. Chaos makes used of narrator.device and reqtools.library.5 The only other files required are the executable chaos and the data file pool.ssc both of which must reside in the current directory when Chaos is started. The program cannot be started from the Workbench. Get a CLI and change to the directory containing chaos and just type chaos.
The archive contains some of the levels. These can be loaded with the Load option and experimented with. Eventually the `E' will be the exit to the next level, but it is not currently supported.
