In Fatal Floors by FaultyMarkus Games on Roblox, your objective is to ride an elevator deep into abandoned subterranean facilities, explore four isolated wings, gather ores and valuables, and sell them at the elevator Sell Bin to meet randomized Coin Meter quotas before the elevator leaves. Reaching higher depths requires managing scarce inventory slots, coordinating gate controls, and countering line-of-sight entities and environmental hazards.
Core Gameplay Loop and Floor Generation
A run begins in the lobby elevator with one to five players. Every descent drops your team into a central elevator hub bordered by four cardinal wings: North, East, South, and West. These wings do not connect to each other; the elevator serves as the sole bridge between all four sections of the map.
Floor 1 is entirely deterministic across all runs. It always loads the Facility map, spawns five Iron Ores, contains only one entity (the Blob), and sets an initial Coin Meter quota of 8 credits. Completing Floor 1 guarantees an early credit payout and introduces the basic looting loop.
From Floor 2 onward, generation becomes procedural. The layout, map theme (such as Facility, Mansion, or Hedge Maze), item spawns, and Coin Meter quotas randomize. Deeper floors demand increasingly higher credit quotas to unlock descent. Each wing gate features a wall-mounted button that allows players to seal off doorways, creating safe zones or isolating hostile monsters. Once the Coin Meter quota is satisfied, an elevator departure timer triggers, typically giving teams between 15 and 30 seconds to board the elevator before it descends to the next floor.
Entity Guide and Survival Tactics
Monsters and environmental traps prevent straightforward scavenging. Entities appear according to fixed floor danger tiers early on, becoming mixed as you plunge deeper into the facility.
| Entity / Hazard | Earliest Floor | Threat Profile | Weakness and Survival Tactic |
|---|---|---|---|
| Blob | Floor 1 | Roams corridors, screaming continuously. Deals heavy contact damage. | Jump directly onto its exposed ribs ("teeth") to hop over it without taking damage. |
| Pit / Void | Floor 1 | Gaps in walkways, broken bridges, and elevator shaft drops that cause instant death. | Stop at every vent exit or doorway and inspect ground tiles before sprinting across rooms. |
| Thorns | Floor 2 | Expanding green bushes that slow movement, lower jump height, and drain health. | Avoid stepping into them; clearing them or bypassing rooms requires careful routing or tile removal. |
| Weatherman | Floor 4–5 | Mechanical walking robot that patrols, scans with a rotating head, and charges. | Relies strictly on line of sight. Cannot enter vents. Hide behind obstacles or slam gates in its face. |
| Cave Crawler | Floor 6 | Fast arachnid-like hunter that stares for 3 seconds before sprinting. Speed increases over time. | Breaks pursuit if you break sight lines. Slams doors in its face to trap it; it becomes docile when cornered. |
| Giant Kiwi | Floor 6–8 | Territorial bird guarding a nest containing 3 to 4 eggs. Extremely fast when provoked. | Steal eggs while it faces away or coordinate with a teammate at the gate to shut the bird out. |
| Bone Hound | Floor 6–9 | Apex predator that triggers a screen warning: "Warning, dangerous entity detected." | Emits sniffing and barking within 20–30 studs. Only move past when it is sleeping (roughly 20-second sleep cycles). |
| Stinger | Random | Ceiling-mounted hazard that drops downward when players pass underneath. | Hug room perimeters and avoid lingering beneath overhead machinery. |
When tackling the Weatherman, pay attention to audio cues. When its footsteps stop and a rhythmic beeping begins, it is performing a perimeter scan. Breaking line of sight by hiding behind double-stacked crates or turning corridor corners prevents detection. If chased, duck into a vent pipe or cross an open pit bridge, as the Weatherman will track across bridges but cannot squeeze into ventilation shafts.
For the Giant Kiwi, taking an egg immediately triggers pursuit. If you carry a Hammer, you can reposition or delete tiles around the nest. When running eggs solo or in pairs, have one player bait or sprint with the egg while another stands by the wing gate button to seal the room the instant the runner crosses the threshold.
Ore Values and Inventory Management
Base inventory space is limited to two items. Because your carrying capacity is severely restricted early on, managing what you haul back to the elevator Sell Bin determines whether you clear higher quotas.
- Iron Ore: The most common ore found across early facility corridors. Yields modest credit progress toward the Coin Meter.
- Jade Ore: Recognizable by its green glow. Spawns frequently from Floor 3 onward and provides a substantial jump in value over iron.
- Amber Ore: Orange mineral providing high credit returns, commonly tucked into deep vents and side desks.
- Amethyst Ore: Purple crystal representing high-tier loot, capable of fulfilling large chunks of late-game elevator quotas.
- Gold Ore: Rare 5-star ore found in deep or locked rooms that provides massive credit value upon deposit.
- Shards: Special currency found scattered across floors or collected as daily login rewards (2 per day). Shards do not count toward elevator quota progress; they are brought to the lobby to unlock permanent Classes.
If you find healing items, weigh immediate health needs against credit gains. Raw Carrots yield minor health or can be purchased in the shop for 15 credits. Cooked Ham provides 40 HP, restoring half a depleted health bar. Consuming Giant Kiwi eggs restores health, but cooking them on a Campfire significantly increases their healing and credit resale value. In Hedge Maze rooms, drinking from water fountains replenishes lost HP for free.
Upgrade Shop and Elevator Improvements
Between floors, an upgrade billboard drops down on the North side of the elevator. The game alternates between offering free team-voted items and a paid catalog where credits can be spent on tools.
- Bigger Bag: Increases inventory capacity by +1 slot. This is the single highest-priority upgrade in early floors, as expanding carrying capacity from 2 to 3 or 4 dramatically reduces the number of trips required per wing.
- Storage Pot (150c): A placeable tile that holds loose items and ores in the elevator. It prevents inventory clutter, keeps spare revives safe, and stores surplus ores for later floors.
- Glass Gate: Upgrades standard elevator security doors to transparent glass. Allows players to safely monitor monster patrol patterns and scanning states without opening the door.
- Hammer (150c): Allows players to move, place, or delete specific functional tiles inside and outside the elevator, including barricades and bird nests.
- Glass Breaker: A utility hammer used to shatter reinforced glass windows throughout mansion and facility levels to access sealed rooms.
- Teleporter (750c): Provides a wearable travel tool on a roughly 2-minute cooldown that instantly teleports the user back to the elevator hub from deep wings.
- Reviver / Revor (400c): Allows a living player to pick up a fallen teammate's head and restore them to life. In solo play, revives cannot self-resurrect you upon death and should be sold for credits instead.
- Campfire (750c): A placed utility tile used to cook food items, transforming raw eggs and rations into high-value meals.
Class Selection and Lobby Progression
Shards earned during floor exploration can be redeemed in the lobby Classes Shop to unlock permanent roles that grant specialized starting loadouts.
- Chef Class: Spawns with a personal Campfire, a Ham, and a Carrot, alongside solid baseline health and backpack space. Excellent for sustaining party health across long descents.
- Hoarder Class: Built specifically for high-capacity ore farming. Grants additional backpack slots and bonus starting money, making quota completion faster.
- Builder Class: Spawns equipped with a Hammer and two Storage Pots. Players can construct pipe barricades to block advancing entities like the Weatherman and Cave Crawler while freely manipulating Kiwi nests.
- Teleporter Class: Spawns with an active Teleporter. Highly effective for solo scouts who venture into the furthest corridors and need instant returns to the elevator.
- Doctor Class: Team support role centered around medical supplies and rapid teammate revival.
Exploration Strategy and Team Communication
Surviving beyond Floor 10 requires structured sweep patterns rather than split looting.
First, sweep one wing at a time. Send the entire team into a single cardinal direction in a clockwise rotation. Clearing a small or medium wing as a unit ensures all ores are retrieved in one pass. Once a wing is empty, press the gate button to lock it permanently. Sealing finished wings reduces the territory you have to monitor and prevents roaming monsters from sneaking into the elevator.
Second, designate a dedicated gatekeeper when handling aggressive entities. When retrieving Kiwi eggs or drawing a Weatherman away from an ore-dense room, have one player stand directly on the gate button. As soon as the looter sprints past the threshold, the gatekeeper drops the door, cleanly trapping the monster on the other side.
Third, save surplus high-tier ores in Storage Pots. Quotas scale up sharply on deep floors. If your team discovers Amethyst or Gold Ores on an easy floor where the Coin Meter only requires basic Iron or Jade, drop the surplus into a Storage Pot inside the elevator. This bank of reserve wealth provides a safety buffer when you encounter hazardous layouts with minimal ore spawns.
