Miller quickly turned around to see who had screamed. It was Reina. A Xeno had jumped on top of her. It's mouth was stretched out, almost about to bite into her. Miller's first instinct was to shoot, but remembered that the blood of the Xeno's were acidic.Before he was able to respond to any kind of plan, Regi Bergmann tackled the creature off of her. 

As soon as he tackled him Darren shouted, "Get away from it!" Regi hit it a couple times at it squirmed but was able to get up from and away from creature. 

A grenade landed right beside the Xeno. Before the Xeno could react, the grenade exploded causing a loud bang. The Xeno had lived but it was missing some limbs, crawling and screaming as it tried to run away. It's blood seeping on the asphalt, melting it.

Miller watched, surprised at how fast Darren was a ready to kill the creature.
