Dungeon Helper is a program designed to make it easier to play P&P games like Shadowrun or Dungeons&Dragons over the Internet.
Basically it is a Whiteboard where players can place a little pin to indicate where they are standing and where they are looking. The Gamemaster can add Pictures (like Floorplans), various objects (like recangles, lines etc.) and NPC’s. He can also add little bits of information to Players and NPC’s, like their hitpoints and class.
Other features include a chat, the abillity to roll any number and kind of dice inside the programm (i.e. roll 10 D20 or 2 D6) and much more!
