在21世纪，一个被称为泰隆人的外星物种带着和平的承诺来到了地球。他们撒谎了。他们真正的目的是统治我们。经过多年的斗争，泰隆人已经灭亡，留下了更具侵略性的生物。。。阿塔武斯。我的名字叫蕾妮·帕尔默。我的任务是阻止这个新物种主宰我们的星球。这是地球的最后一次冲突。

In the 21st century, an alien species, known as the Taelons, came to earth with a promise of peace. They lied. Their true agenda was to dominate us. After years of struggle, the Taelons have perished, leaving more aggressive beings in their wake... the Atavus. My name is Renée Palmer. My mission is to stop this new species from dominating our planet. This is earth's final conflict.
