Alien- Blood Infection

It took a step toward Brenna, and its tail whipped around and struck her across the face with a loud crack, just the way a real whip would’ve sounded.
Brenna was knocked to the side and collapsed onto the floor. Her cheek had been flayed by the tail’s barbed end, and blood streamed from the wound. She grimaced in pain and raised her pistol, clearly intending to fire it again.
Then she screamed.
Some of the viscous black goo had still adhered to the tail, and now it began eating into Brenna’s flesh. Her uninjured skin began showing signs of infection, and the lesions and pustules came on swiftly. Tamar guessed this was due to the gunk getting into an open wound, giving the virus direct access to her bloodstream. The woman began coughing violently, and her gun hand shook so hard that when she fired, her bullet went wide and missed the Necromorph entirely.
