"A two-headed monster!"

A mechanical routine followed: kick the door, raise the gun. Kick the door, scan, and search. If the room was empty, they'd move on. If they found someone, they'd aim at the object's legs and fire a volley to hinder them.

Every time a door was kicked open, Jonathan's nerves would tighten, a process repeated over a dozen times.

Behind the doors, there might be empty rooms, innocent crew members, a ferocious Xenobiotics creature, or a Heteroblood. Sadly, they hadn't encountered any living human, except the shapeshifting monster that initially attacked them.

The most dangerous things often lurk in the depths. 

Breaching doors was like playing blind box, playing with their hearts racing. It felt to Jonathan as if he was bungee jumping off a cliff, his inner tension stretching with the elastic cord.
