For Millennia, a secret world of otherwordly entities have existed, thrived and conspired against us from within Earth's depths. Concealed in global cave systems, mountain bunkers, Antarctic caverns and constructs deep beneath the oceans, these malevolent beings have spawned a new race of Alien-human hybrids and have been using thought control to manipulate humanity. They are indestructible, unwavering and are fulfilling their objective to extract us. Earth is no longer ours and maybe it never was.
