'The Pit' is a multi-layered, often vertical level, typically set in a deep mine, quarry, or industrial excavation site. This level emphasizes vertical movement, platforming, and dealing with enemies from above and below.

- Pit Entrance: You'll start at the top or bottom of a large pit. Clear the initial enemies and look for ways to ascend or descend.
- Vertical Navigation: The level features numerous platforms, elevators, and precarious ledges. Careful platforming is often required. Watch out for falling hazards.
- Enemies Above and Below: Expect enemies to attack from all angles. Cultists and Fanatics might snipe you from ledges, while Hands and Spiders can ambush you from below. Death Shrouds are also common in open pit areas.
- Mining Equipment: You'll encounter mining carts, drills, and conveyor belts. These can be environmental hazards or used to access new areas.
- Finding the Keys: You'll need to find keys (e.g., Skull Key, Spider Key, Dagger Key) to unlock various sections of the pit or activate machinery. These are often located in small offices or hidden caves.
- Environmental Puzzles: You might need to activate a crane to move debris, or reroute power to an elevator.
- Cultist Priests and Fanatics: These tougher enemies are common, often guarding key areas or ambushing you in tight passages.
- Exit: The exit is typically a large elevator or a hidden tunnel that opens once all objectives are met and you've navigated the pit's depths.
This level requires good spatial awareness and precise movement. The Flare Gun's primary fire is excellent for picking off distant snipers, and Dynamite can clear out groups of enemies in tight shafts. Always look up and down for threats.
