99 Nights in the Forest

99 Nights in the Forest is a co-op survival horror game on Roblox where teams of up to 25 players must survive 99 in-game nights in a dark, hostile forest while defending a campfire from a stalking bipedal Deer Monster and its Cultist followers. Created by Cracky4 (also known for Break In and Break In 2) under Grandma's Favourite Games, the game launched in March 2025 and has surpassed 26 billion visits, 6.98 million favorites, and 150K-250K concurrent players - placing it among the top co-op survival experiences on Roblox.

Unlike typical Roblox simulators, this is a genuine survival game with hunger management, crafting, class-based roles, and escalating threats. The day/night cycle structures everything: players gather wood, stone, and food during the day, prepare defenses at dusk, and fight to keep the campfire lit through every night. If the campfire goes out, the entire team loses its safe zone. The narrative goal is finding and rescuing four missing Kids hidden in the forest. Players choose from 33 distinct Classes - each purchased with Diamonds and defining starting gear and survival role:

• 🏠 Campfire - the central safe zone and top survival priority; keeping it fueled with wood through every night is the team's shared responsibility, and the tension of managing its fuel is the game's central mechanic
• ⚔️ Class system - 33 classes from the entry-level Camper (10 Diamonds, flashlight only) through mid-tier Ranger (70 Diamonds, revolver) and Chef (150 Diamonds, food production) to endgame powerhouses like Cyborg (600 Diamonds, alien armor and laser cannon) and Necromancer (600 Diamonds)
• 🗺️ Biomes - the world currently includes the default Forest, the Jungle Biome (released March 2026) with its Cat Entity and Fight Pits, and the Mini Fairy Biome (released March 2026) with fairy enemies and unique buildings
• 💎 Crafting - weapons, armor, tools, and structures built from gathered materials; the Recycler station (added March 2026) converts higher-tier materials into lower-tier ones, reducing waste
• 🏆 Hard Mode - optional difficulty with heightened entity aggression, reduced resources, and Corrupted Items; rewards more Diamonds per run for players willing to push the challenge

Diamonds are the persistent currency earned from rare chests, completing achievements, and surviving all 99 nights - spent to permanently unlock classes across all future sessions. Team composition matters: a well-rounded group needs Medics for healing, Lumberjacks for wood production, Chefs for food at scale, and combat classes like Rangers and Pyromaniacs for monster defense. Gems - the secondary currency rewarded through events and other sources - fund minor shop purchases and seasonal event rewards like Candy during Halloween.

99 Nights in the Forest sits at the top of Roblox's cooperative survival genre, with a Fandom wiki at 99-nights-in-the-forest.fandom.com spanning over 4,000 pages and a biweekly update cadence that has added two full biomes and new mechanics since launch.
