"The onslaught of monsters" is a typical conflict-driven scenario concept, commonly seen in narrative fields such as film, television, games, and literature. Its core lies in creating a sense of tension and dramatic momentum through "the invasion of unknown threats," thereby evoking the audience’s sensory impact and emotional resonance.

It usually starts with "the disruption of daily order"—this could be the sudden appearance of a giant creature in a peaceful town, or the intrusion of an eerie entity into a confined space. The form of the monster often carries symbolic meaning: it may represent nature’s retaliation against humanity (e.g., Godzilla), or serve as a metaphor for the fears deep within human nature (e.g., Alien).

In terms of scene construction, a sense of oppression is often intensified through environmental contrasts (bustling city → desolate ruins), sensory stimulation (roars, distorted appearances), and character reactions (panicked escape, desperate resistance). Ultimately, it aims to explore themes such as "survival," "confrontation," and "choices of human nature," making it a classic setup for delivering tense narratives and engaging the audience’s emotions.
