xenomorph

You crawl alone along a narrow iron pipe. Ahead lies a fork and torn wires. Your tool bag scrapes loudly against the metal. Suddenly, a grate crashes down from above. Technician Lewis falls right in front of you, followed by a massive black creature. The monster silently pins Lewis to the floor and crunches his head open with its retractable jaws. The creature is blind, but its hearing is perfect. It begins to devour the body three meters away. The dead man's radio flies right into your fingers. A terrible wheezing and loud static echoes from its speaker throughout the ventilation system. This noise is about to attract the monster. The way back is long, and backing up will be too slow. The speaker emits another loud burst of static. Your move.
