"Solace 1-5, long-range data just came in. You're gonna wanna see this.

We detected an odd set of readings in the Nevada desert just off Piper Canyon. After we detonated the ALLEGIANCE Black site, my bet was: they were setting up a new facility to take its place. Another project building right under our noses... 

Well, the recon team just came back, Commander.

And it's not ALLEGIANCE. It's one of ours.

Delta Division made it out. And they've been hiding here for 6 years!

With your okay, we'll send a squad in. If we establish contact, we'll see how many they have. How well-equipped.

Once we have the intel, we can get them out of there.

You were right, Commander. We're not alone. And the fight's not ever yet."
