99 Nights in the Forest Bat Entity Guide, & New Codes?

The latest update in 99 Nights in the Forest adds a new layer of fear to the game with the arrival of the Bat Entity and the introduction of underground cave systems. This update expands exploration, introduces tougher enemies, and hints at even darker content ahead. If you’re jumping in for the first time since the update, this guide breaks down everything new and how to survive it.

Overview of the Cave Systems

The biggest change is the new underground cave network. These aren’t simple tunnels — they twist, branch, and create multiple paths that can easily confuse you. Light sources are essential, and entering without prep is a fast way to get lost.

Inside the caves, expect:

• Tight corridors
• Sudden vertical drops
• Hidden rooms
• Ambush locations

Players should treat the caves differently from the surface. Sound plays a bigger role, and movement may attract unwanted attention.

The Bat Entity

The star of this update is the Bat Entity, a new predator lurking deep within the caverns.

What to know:

• It has poor vision, so movement and noise matter more than line-of-sight.
• Its scream can stun and reveal you, giving it an advantage during pursuit.
• Hiding in tight spaces or staying still can help you avoid detection.

The best approach is patience. Running, dropping items, or breaking objects increases sound and makes encounters more likely.

New Cultist Variants

Alongside the Bat Entity, new cultist types have appeared. These are stronger, more aggressive, and clearly tied to whatever darkness exists underground.

They:

• Patrol deeper regions
• React faster than older cultist types
• Sometimes move in pairs

Weapons and stealth both work, but retreat is still a valid strategy if you’re unprepared.

Locked Sections and Future Secrets

Some areas in the underground are currently sealed off. The update notes confirm that these zones will be opened in later patches, meaning the caves will expand even further with future content.

This suggests:

• More enemies
• Possibly new relics or items
• A deeper storyline connected to the forest

For now, players can only speculate.

New Codes

As of this update, no confirmed new codes have been released. Codes are common after major updates, so it’s worth checking the game’s social pages or patch announcements. Keep an eye out — developers often release them days after update rollout. Also check out our 99 Nights in the forest Codes list for more rewards!

This update pushes 99 Nights in the Forest into a darker, more survival-heavy direction. With the underground map, tougher cultists, and the terrifying Bat Entity, exploration now requires more strategy and caution. If you’re up for a challenge and ready to learn the new systems, the cave update adds rewarding but risky content worth exploring. Enter prepared — the forest isn’t the only thing watching anymore.
