The Roblox survival horror game 99 Nights in the Forest has rolled out its Volcanic Biome Update on September 13, 2025, introducing a fiery new environment packed with challenges and rewards. This is Part 1 of the update, with Part 2 scheduled for September 20, 2025. For the next two weeks, the Volcanic Biome temporarily replaces the Snow Biome, after which it will join the random rotation alongside the Forest and Snow Biomes. The update focuses on volcanic-themed gameplay, including hazardous lava pools, new enemies, powerful items, and a central volcano mechanic for sacrifices and loot.
Drawing from official patch notes and community guides, this article details every new addition and change. Players will need to adapt to the intense heat, navigate deadly terrain, and leverage new tools to survive the 99 nights.
The Volcanic Biome: Terrain and Environmental Changes
The Volcanic Biome transforms the game’s landscape into a barren, ash-covered wasteland with dark grey ground and limited vegetation. Leafless trees provide 3 logs when chopped but no saplings, while dry bushes may hide Scorpion Nests. Lava pools are a key hazard, dealing damage over time to most entities and players upon contact (exceptions include the Deer and Owl). Most items burn or disappear in lava, adding risk to exploration and resource management.
During this update phase, the Owl no longer spawns, shifting emphasis to volcanic threats. The biome includes glowing lava flows, volcanic rock formations, and an active volcano where players can sacrifice offerings—such as Cultist corpses or even dead teammates—for loot. This mechanic encourages strategic gameplay, with sacrifices potentially influencing rewards or events.
New Entities and Mobs
Two new entities heighten the danger in the Volcanic Biome:
- Scorpion: A hostile mob that spawns from nests in dry bushes, serving as the primary wild threat in this environment. Defeating them is key for survival and earning badges.
- Mega Cultist: An enhanced version of the existing Cultists, posing greater challenges in combat and tied to sacrifice mechanics.
These additions complement the biome’s theme, requiring players to engage in more intense battles amid hazardous terrain.
New Structures, Locations, and Chests
The update introduces the Volcanic Biome as a new location, complete with interactive elements:
- Volcano: The focal point for sacrifices, where throwing in Cultists (alive or dead) yields valuable loot.
- Infernal Chest: Special chests scattered across the biome, containing rare items like the Inferno Sword.
Brand-new structures enhance exploration, though specifics like churches or ruins are integrated into the biome’s design for thematic immersion.
New Items and Weapons
Four fresh items bolster player capabilities in this fiery setting:
- Inferno Sword: A powerful melee weapon that sets enemies on fire and instantly cooks raw food from consumable mobs. Obtained via volcano sacrifices or Infernal Chests, but it burns in lava.
- Wildfire Potion: A throwable item that creates a temporary lava pool on impact, ideal for traps or area denial.
- Infernal Sack: A 20-slot inventory item that automatically cooks raw food placed inside, streamlining survival.
- Crossbow: A ranged weapon with infinite ammo, uniquely resistant to lava, making it perfect for the biome’s hazards.
These items emphasize fire-based combat and utility, fitting the volcanic theme.
New Badges and How to Earn Them
Four limited-time badges encourage specific achievements, available only during the event:
| Badge Name | Description/Requirement | How to Obtain |
|---|---|---|
| Resourcefulness | Reward for clever resource use via sacrifices. | Sacrifice a Cultist corpse (or dead teammate) at the volcano for loot. |
| Pest Control | Tied to eliminating Scorpions. | Defeat Scorpions or clear their nests in the biome. |
| Metaworking | Involves advanced crafting or metal-related tasks. | Craft items or achieve milestones related to new gear (details emerging from community play). |
| Volcanology | Mastery of volcanic elements and exploration. | Complete tasks like multiple sacrifices or surviving biome hazards. |
These badges unlock exclusive rewards, motivating players to engage fully with the update.
Additional Changes and Gameplay Tweaks
Beyond core additions, the update includes quality-of-life improvements:
- Biome Rotation: Post-event, the Volcanic Biome has a chance to spawn randomly, ensuring variety.
- Visual Overhaul: Ash-covered terrain, lava flows, and rock formations create a dynamic, immersive atmosphere.
- No New Codes: Progression relies on in-game actions rather than redeemables.
This update enhances the core survival loop with high-stakes exploration and combat.
