ngPAWS (next generation Professional Adventure Writing System) is an engine for creating text adventure games (aka. interactive fiction) that can be run in any modern browser (wether online or offline).

ngPAWS is strongly based in Professional Adventure Writing System for the ZX Spectrum home computer, a system widely used in Europe in the late 80s and 90s (released in America as Timex home computer). ngPAWS is also based in Superglús, and is in fact a rebuild of that authoring system using javascript instead of Glulx virtual machine.

ngPAWS is avaliable for Windows, Linux x86/arm, and OSX.
