If you enjoyed Starship Troopers, then Richard Garriotts Tabula Rasa has an instance for you! The Kardash Atta Colony is basically an ant hill, but with ants about 12 feet tall who work in groups. You're going to need a lot more than a can of Raid to make it through this one. Ten Ton Hammer took a second look through this instance and updated the guide with some key layout changes, and more strategy tidbits.
On the desolate planet of Arieki is one of many rugged and unforgiving areas called the Torden Plains. This zone offers players their first glimpse of a unique species called the Atta whose colonial like nature makes them not only dangerous, but challenging to fight. West of the Irendas Penal Colony, the Atta have built a "nest" within the mountain providing themselves solid defense and a home for their queen.
