We'll find out there is a huge installation shaped like a ring that the Combine have been preparing, possibly to be used to destroy Earth and Xen. You'll be sent by the Gman to stop them and use the weapon againist them. Soon you and them realize the true story behind the installation. Prepared eons ago to be used as a last resort againist the spread of headcrabs by killing all possible host organisms, it has a maximum range of 25,000 light years. 646 Innocent env_spark tells him that after one fires, the others do to, effectively ending the threat of headcrabs by starving them. As both humans and combine realize the enourmity of these rings, they create an uneasy alliance to dismantle the system. The Gman abandons Gordon after the mission is accomplished, and soon after, war resumes between the Combine homeland againist Earth and Xen. In the final battle between the Combine againist the doomed Human And Xen forces, Gordon is about to be killed
