99 Nights in the Forest is a co-op survival horror game on Roblox made by Grandma's Favourite Games, and it became one of the platform's biggest horror breakouts in 2026. The setup is simple to describe and brutal to actually pull off: you and your group get dropped into a cursed forest, and you have to survive up to 99 nights, rescue four missing children scattered across the map, and keep your campfire burning the entire time, because the fire isn't just for warmth, it's the only thing standing between your group and what's stalking you in the dark.
Picking a class before the run starts
Before you even spawn in, you choose from a roster of over 20 classes (the game has expanded to 39 total options as of mid-2026), each priced in Diamonds and built around a different playstyle. Entry-level picks like Base Defender cost around 40 Diamonds and are meant for players still learning the loop, while specialist classes like Big Game Hunter (600 Diamonds) or Assassin (500 Diamonds) come with stronger starting gear and passive perks but expect you to already know what you're doing. Every class leans toward one of four broad jobs: crafting, healing, trapping, or ranged combat, and none of them are strictly better than the others, they're built to be combined.
Why team roles matter more than solo skill
If you're playing with a group, the runs that go well are almost always the ones where the team splits into fixed roles instead of everyone doing a bit of everything. A typical efficient split looks like one player as scavenger, running the map for loose materials, one as hunter, keeping the group fed and collecting pelts, and one as lumberjack, keeping the wood stockpile from running dry, since wood underlies almost every early recipe. Random improvisation works fine for the first night or two, but once the resource math kicks in, an uncoordinated group burns through supplies far faster than one with assigned jobs.
Crafting and why costs keep climbing
The game currently tracks 104 craftable items pulled from ingredients like Wildfire weapon parts, Scorpion Shell pelts, and farmable Corn, feeding into 31 total crafting recipes plus 6 separate campfire upgrade tiers. Most early crafting happens at the Anvil, where something as simple as a bandage only needs common materials, but here's the catch that trips up new players: the resource cost for a given item goes up every time you craft another copy of it. That means stockpiling one type of gear early is efficient, but trying to mass-produce the same item late into a run gets progressively more expensive, so spreading crafting across the team's different needs matters more than hoarding one thing.
The campfire is your clock, not just your light source
Keeping the campfire fed and upgraded should be the first priority in any run, because everything else, crafting, resting, even your visibility to the game's main threat, is tied to it staying lit. Letting it die out isn't a cosmetic setback, it directly changes how dangerous the night becomes.
The Deer changes behavior as the nights add up
The Deer is the game's central threat, and it does not behave the same way twice across a full run. During Nights 1 through 10, it mostly just watches your camp from a distance and vanishes the moment you point a light source at it, unsettling, but not lethal on its own. Between Nights 11 and 50, it turns into an active stalker that will hunt down and extinguish your campfire on purpose, and if the fire goes fully out while it's nearby, it can kill a player outright. Past Night 50, it gets significantly worse: it can sprint, break straight through wooden walls that would have stopped it earlier, and by that point simple light sources stop working as a deterrent, you need Holy Light flares to actually push it back.
The Fairy Biome side event
Added in a January 2026 Mini Biome update, the Fairy Biome is a limited-time area that spawns independently from the main map, wrapped in permanent fog and dotted with oversized mushrooms. Its enemies are Fairy Wolves, also called Mushroom Wolves, which drop Acorns when killed. The whole point of the biome is reviving the Mother Tree at its center: you plant the Acorns you've collected at four glowing points along the tree's broken roots, and once all four are reconnected to the enchanted pools around it, the tree revives and a Blue Chest at its base opens automatically, usually holding a Strong Axe and an Enchanted Farm Tablet. Experienced players sometimes skip the Enchanted Farm reward itself since it's a slower long-term investment, but the Strong Axe alone is often worth the detour.
Practical tips for a first full run
Get wood and get your campfire upgraded before you do anything else, it's the one resource every other system depends on. Try to secure a Bunny Foot early too, since it's useful for trading with other survivors you run into. And if you're in a group, agree on roles in the first few minutes rather than after your first bad night, because by the time the Deer starts actively hunting your fire past Night 10, an unorganized team is already behind.
