The Siege Editor

Gas Powered Games' official Dungeon Siege website has been updated with a list of features that the Siege Editor will provide once it is available. Here's an excerpt:

    Assemble terrain using over 3800 different nodes, from spooky underground caverns to soaring high-rise towers. Choose from 32 different texture types that can be swapped between with the press of a button, and eight complete node sets to help you create your own worlds. Add rain, snow, or fog to the region to enhance the atmosphere.
