"They left downtown." The woman sighs, obviously skipping over the personal parts... mostly. "...I'm leaving this note hoping you will not come here read it, but if you do, we had a very rough couple of days: those things swarmed the front door, and HERC barely managed to hold them back. They were just a squad of five, and there were too many hallways to watch."

She pauses, skipping over another personal part, likely. "...we blocked the rear and side stairwells, and formed a bottleneck we could defend. Overnight, the attacks trickled off, and in the morning an HERC chopper landed on the roof. After they secured floors 5 to 12, they started evacuating people to the Stadium, which is their main base now. I overheard some of them talking about more outbreaks happening up north..."

"More?" Not good news.
