SpeedTreeRT(tm) SET TO DEBUT IN MYTHIC ENTERTAINMENT'S"TRIALS OF
ATLANTIS" Expansion Pack To Be Released Oct. 28th
'The Difference Is Night and Day'

COLUMBIA, SC - October 21, 2003 - SpeedTreeRT(tm), Interactive Data
Visualization's revolutionary tree-creation system, will be introduced
to the game playing public October 28 with the release of "Dark Age of
Camelot: Trials of Atlantis," the latest expansion for Mythic
Entertainment's wildly popular online game, "Dark Age of Camelot."

"Trees are the single most important element of many outdoor
environments," said Mark Jacobs, president and CEO of Mythic
Entertainment. "The difference is night and day between SpeedTree and
any other real-time tree solution."

"Dark Age of Camelot" and has received "Game of the Year" accolades from
both Computer Games Magazine and Computer Gaming World, and "Trials of
Atlantis" will continue the tradition of excellence. Featuring
SpeedTreeRT, a variety of other graphical upgrades, a series of epic
trials and a newly revealed half-submerged continent, "Trials of
Atlantis" will further extend the "Dark Age of Camelot" experience.

SpeedTreeRT brings a number of innovations to virtual play, including
level of detail and billboarding techniques that make the trees look
full and real from any direction, even under or inside the tree. The
technology, praised earlier this month by Game Developer magazine for
its "perfect balance between speed and quality," features a large
library of conifers, broadleaves, palms, shrubs, flowers and fantasy
trees, but also enables the creation of new trees and plants on the fly.

"We expect players to be astounded by the quality of foliage in Trials
of Atlantis," says IDV President Chris King. "Mythic has done a
fantastic job with SpeedTree. It's a great place for our trees to be
seen for the first time."
