In the Island safe house, Snowden shows everyone the Anti-Carrier Luminal Agents and tells them what happened to Brianna.

Zoey: Where's Brianna?

Snowden: *sighs* She's gone.

Zoey: *gasps and covers her mouth*

Louis: Oh, no.

Snowden: Seeing her all cut up and half-naked, I already knew it wasn't an easy death. Still, in her final moments, she told us where these Agents were.

Louis: She still tried to help us?

Snowden: *breath trembling* Yes, Louis. I tried to save her, but she knew it was too late for her. But it's not too late for us. Come on, gear up. We need to be absolutely safe before you guys take these.

Francis: Who in the hell were those pieces of shit?

Snowden: Unfortunately, I don't have a clear answer for you. Could be terrorists, Chinese or North Koreans. Can't recognize their language.

Zoey: So, back to the sailboat then?

Snowden: Yeah, on me.

With evacuation now the priority, the survivors retrace their steps around the flaming wreckage of fighter jets and through the CEDA tents. Snowden tries to turn the elevator on from its Flight Deck controls, but still no luck.

So he, Zoey, Louis and Francis take the stairs once again to Hangar Bay 1. They expect to make a quick pit stop at the Mess Hall safe house, only to find it breached, filled with craters and unsafe.

Snowden: Clear.

Louis: Aw, man. The Mess Hall is trashed.

Snowden: Safe house doors are down. Tons of craters.

Zoey: Guess that group who attacked us were in a hurry.

Snowden: Alright, no stopping here. Let's head straight to the Well Deck.

Unsurprisingly, they encountered just a handful of Commons, Uncommons and Specials. Everyone can guess why that is the case.

Closing in on the Well Deck, there is good news and bad news. The bad news is the door to it has been blocked by a dead Tank and two Chargers covered in sticky Spitter goo.

The good news is the Well Deck's control room is a safe house, and it can take the group to where they want to go. So they regroup and rest for a bit, as they do not expect the Well Deck's door to be quiet.

Francis: Okay, seriously, these ass clowns are real annoying.

Snowden: Don't worry, we can take the Control Room down there.

Louis: At least they didn't wreck this safe house.

Zoey: Oh, bullshit! Those sons of bitches closed the damn door!

Snowden: But it looks like the sailboat's still intact. And if they can close the door, we can open it back as well.

Zoey: *sighs* Okay. Everyone assemble in the safe room.

Snowden: Ready up, people. I doubt this'll go quietly.

We're safe... for now.
