The Combine (HL2) VS Rick Prime

Been wondering this for a while. For the sake of making it close to fair, we'll give both sides a week of prep time. Rick Prime is allowed to use the Omega Device, and the Combine are able to use their whole army in any way they please, as long as it fits within the lore of HL2.

Winning for Rick Prime means either destroying the government of The Combine, or forcing them to leave the CFC.

Winning for The Combine is to kill Rick Prime, and all his backups. There should be no way to bring him back at all.
