The trailer for the film quickly covers different psychological states like hallucinations and claustrophobia through shots showing disorientation and dust. It only shows brief glimpses of the creatures to build suspense rather than revealing them fully. Both the poster and billboard effectively portray horror through use of dark colors and images suggesting blood and struggle. The poster highlights the involvement of the studio known for films like SAW and raises expectations through quotes comparing it to Alien. The billboard creates an unsettling image through a face-like pattern in the dust and focus on the main character's face in a pool of blood.
