This page is a quick script reference for Fallout. The game is script-driven, but due to its age and era, it does not have human-legible scripts. The goal is to help users parse these scripts and understand that roll_vs_skill(dude_obj, 14, 0) means a roll against Speech with no modifiers applied.
In Fallout 2, these were consolidated into DEFINE.H.
