What D20PRO is
D20PRO is a multiplayer virtual tabletop for role-playing games that automates gameplay while leaving Game Masters in control.

Maps support fog of war, hidden areas, distance and line-of-sight measurement, map libraries, and drawing tools for images. Game Masters can approve or delay actions, edit rules, create scripts, and distribute private notes and files as handouts. D20PRO supports online sessions and face-to-face play without an internet connection. It can import game information from Hero Lab and PC Gen. A free Guest License allows a player to join when the host has an open guest seat. The Player License is $10, paid once, and the GM License is $42, paid once.
