Connor looked at her before returning to fight the aliens, ghost was going through the sky. Taking down aliens, in the sky. That's when he felt a shot hit his back he grunted in pain before firing more shots at them. He soon found frost, he landed on the roof him and frost started firing. 

Soon though, ghost felt the heating system starting to fail, the suit kept getting colder each time he hit frost or blaster him with his pulsars. By the time they broke apart, Michael was shaking. He took off the helmet and dropped it to the ground before he started attacking frost once more. Exchanging blows each time, frost had half of Michael's body hanging off of the roof.
