Can she make it out?

No.

Mara ran as fast as she could, these were clearly Succubi who had been trapped in this tunnel and unable to escape. Without mortal souls, they must have completely lost their humanity, turning them into these feral beasts.

And she was about to become one of them if she couldn't escape. She screamed as she stumbled over the cars, knowing that she was stuck between the ferals and the two Succubi outside. Either way, she was not going to be able to escape the virus, but maybe...

"FUCK!" She screamed as she tripped over some debris, spraining her ankle just short of the barricade. She felt a hand grab her ankle and turned around to see the girl from her college grabbing her, salivating. "No... please... anyone... HELP!"

She could hear her scream of help echoing through the tunnel as the Succubi reached for her, ripping her clothes off.
