Stand alone expansion pack to Homeworld, made by Barking Dog Studios and published by Sierra Entertainment.
This is the stand alone expansion/sequel to the original Homeworld game. These games are very fun 3drts games. The controls are perfect, the graphics were amazing for its time, and the story is awesome. In cataclysm, you control a large mining ship called the "Kuun-lan", that , with out meaning to, unleashes a bio mechanical infectious organism upon the galaxy. They then rush to contain it.
