The Descent (2005): Is a claustrophobic survival horror about a group of women trapped in an uncharted cave system — only to discover it's inhabited by terrifying humanoid creatures. Combining primal fear of darkness and confinement with creature-feature violence, it's a modern horror classic.

The Descent: Part 2 (2009): Continues the nightmare as a rescue team ventures into the same cave system, only to be hunted by the crawlers once again. Mixing claustrophobic tension, monster attacks, and survival stakes, it doubles down on gore and terror.
