Overview
The Metro is a procedurally generated dungeon system where players descend through randomly assembled tunnel networks, fighting enemies and looting containers on their way to a Metro Station. At the station, players clear the area and claim a Metro Fob — a special currency used to purchase permanent account upgrades that improve future runs. After clearing a station, and progressing further the tunnels become progressively harder with random modifiers applied to the next leg of the run. Players can continue deeper, use a Metro Cart to skip ahead, or exit and return later.
The Metro supports both solo play and parties of up to 8 players. Separate leaderboards track the highest difficulty reached solo and in a group, as well as total stations unlocked over a character's lifetime.
How It Works
Starting a Run
Speak to the Metro entrance NPC at the hub and choose to enter. If you are in a party, all nearby party members will join the run automatically. A new tunnel network is generated starting from difficulty level 0.
Tunnel Generation
Each Metro floor consists of randomly connected area maps — abandoned metro tunnels, sewers, caves, and maintenance passages. The generation works as follows:
- Entrance: You always enter from the side you arrived from, connected by a tunnel door or passage.
- Passages: Each map can generate additional passages to unexplored areas with a random chance. Maps with only one passage are possible (dead ends).
- Early Exits: There is a random chance for an exit to appear, allowing you to leave the Metro before reaching a station — useful if you're low on supplies.
- Metro Station: After navigating enough rooms, the exit to a Metro Station appears. The chance increases the more rooms you've explored.
Enemies
Each new map spawns a random enemy group appropriate for the current difficulty. Enemy types unlock progressively as the difficulty increases:
| Difficulty | New Enemy Types |
|---|---|
| 0 | Bandits, Giant Rats, Molerats, Scavengers, Wild Dogs, Scorpions, Punkers |
| 1 | Ghouls |
| 2 | Thugs, Marauders, Gang members |
| 3 | Small Deathclaws |
| 4 | Children of the Cathedral warriors |
| 5 | Rogues (heavily armed raiders) |
| 6+ | Black Scorpions, Monstrosities (weaker enemies stop appearing) |
As difficulty increases, enemies gain bonus health and deal increased damage with each floor reached.
Metro Station (Final Map)
The station is the end-of-floor objective. It contains:
- Enemy defenders drawn from a separate pool: Fire Geckos, Monstrosities, Children of the Cathedral, Deathclaws, Rogues, and at very high levels, Super Mutant squads.
- A boss enemy that matches the defender type (e.g. a Deathclaw Matriarch with Deathclaw packs, a Super Mutant commander with mutant squads).
- A terminal (computer console). Once all enemies are defeated, use the terminal to claim the Metro Fob and unlock the station.
After claiming the Fob, the station doors open, you receive XP and achievement progress, and a random tunnel modifier is rolled for the next leg of the run. You can then continue deeper through the open tunnel passage, or exit via the stairs.
Extraction Chests
At each Metro Station, each player in the group who has the Extraction Chest upgrade receives a personal loot container. Items placed in this chest are automatically transferred to a permanent Extraction Safe at the Boneyard when the station doors open. Retrieve your extracted items by speaking to the Quartermaster.
Loot Containers
Scattered throughout the tunnels are locked containers. Their lock difficulty increases with depth. Higher difficulties shift the balance toward rarer loot containers instead of standard ones. Containers can contain:
- Caps
- Medical supplies (healing powder, stimpaks, super stimpaks)
- Ammunition of all calibers
- Weapons and armor of progressively higher tiers
- Weapon and armor modifications (T1 through T4)
- Crafting resources and tools
- Skill books and other books
- Explosives and traps
- Collector parts
- Rarely: implants, hypos, repair kits, Sierra chips
- Metro Fobs (starting from mid-tier loot containers)
Beware: many containers are trapped. At lower difficulties you'll encounter bear traps; at difficulty 5 and above, active mines begin appearing instead.
Random Tunnel Modifiers
After each station clear, a random modifier is applied to the next set of tunnels:
| Modifier | Effect |
|---|---|
| Abandoned Tunnels | High radiation, fewer enemies |
| Hunting Grounds | More traps, more loot containers |
| Storage Tunnels | Harder locks, more loot containers |
| Unexplored Tunnels | Heavy radiation, significantly more loot |
| Ransacked Tunnels | Easier locks, fewer loot containers |
| Beaten Path | No traps, less loot |
| Maze | Extra branching passages appear |
| Short Tunnel | Metro Station appears sooner |
| Main Line | Linear path — no extra passages |
| Crowded Tunnels | More enemies, more loot containers |
PvP Encounters
At difficulty 2 and above, after exploring at least 2 rooms, there is a chance your group may cross paths with another player group running the Metro at a similar difficulty. When this happens, both groups are funneled into the same map. Only one PvP encounter can occur per floor.
Metro Fobs
Metro Fobs are the core reward and currency of the Metro system. They are obtained by:
- Claiming the terminal at a cleared Metro Station (1 fob guaranteed)
- A chance to find a second fob from the terminal (requires the Extra Fob upgrade)
- Found rarely in loot containers at higher difficulties
Fobs are spent on:
- Permanent upgrades (see below) — purchased from the Metro Upgrade terminal at the hub
- Metro Cart travel — skipping directly to higher difficulty floors (requires the Cart upgrade)
Fobs are an inventory item and can be traded between players.
Upgrades
Upgrades are permanent improvements to your character's Metro capabilities, purchased with Metro Fobs at the Metro hub terminal. Each upgrade has up to 3 tiers with escalating Fob costs and difficulty milestones that must be reached before the upgrade becomes available.

Upgrade Requirements
To purchase an upgrade tier, you must meet all of these conditions:
- Have the required number of Metro Fobs in your inventory
- Have reached the required difficulty milestone on at least one run
- Have progressed the MetroBlades quest to the required step
- Be in a safe location (not in a dungeon, town control zone, or encounter)
Metro Cart
The Metro Cart appears at the starting station (difficulty 0) and allows the group leader to skip directly to a higher difficulty floor. The maximum floor depends on the Cart upgrade tier. Using the cart costs Metro Fobs equal to half the target floor (rounded down, minimum 1). All group members must be present at the station and the station must be cleared before the cart can be used.
Auto-Doc
Found in Metro Stations when the Medbay upgrade is active. Using the Auto-Doc provides instant healing based on upgrade tier — from basic HP and limb repair up to full radiation cleansing and temporary combat drug bonuses. Only usable after the station is cleared.
MetroBlades Quest
The MetroBlades is a quest line that runs parallel to the Metro system and gates access to higher-tier upgrades.
| Step | Objective | Reward |
|---|---|---|
| 1 | Accept the quest | — |
| 2 | Complete 3 Metro station runs | 500 XP |
| 3 | Purchase the Extraction Chest upgrade (tier 1) | 500 XP |
| 4 | Find and spray over graffiti tags inside Metro tunnels | 75 XP per tag |
| 5 | Complete all graffiti taggings | 500 XP |
| 6 | Assist Blades soldiers — complete the Metro Wave Defense event | 500 XP |
After step 6, a special Metro Wave Defense room can appear in your runs. This is a wave defense event where you protect a Blades outpost from waves of monstrosities, culminating in a boss fight. Completing it rewards 600 XP and transfers your extraction chests to safety. Failure only results in a message — you can continue the run.
Extraction System
Items placed in your personal Extraction Chest at a Metro Station are automatically moved to a permanent Extraction Safe in the Metro hub when the station doors open (either by clearing the station or by completing the Wave Defense event). Retrieve accumulated items by speaking to the Extraction NPC at the hub. The chest capacity depends on your Extraction Chest upgrade tier.
Death and Leaving
- Death: If you die in the Metro, you are removed from the run. If all group members die or leave, the run is cleaned up and all progress is lost.
- Early exit: If an exit spawns in the tunnels, you can leave early to preserve your loot without risking the station fight. You cannot re-enter the same run.
Achievements & Leaderboards
- Metro Stations Unlocked achievement: Tracks total stations claimed over your character's lifetime. Milestones at 1, 50, 100, 200, and 500 stations. Has daily and weekly tiers. Awards a Daily Reward Box (T3) and XP at each milestone.
- Metro Record leaderboard: Highest difficulty reached (group).
- Metro Solo Record leaderboard: Highest difficulty reached solo.
- Metro Total leaderboard: Total stations unlocked.
All group members receive credit when a station is cleared.
Tips
- Start solo to get a feel for enemy scaling before bringing a group.
- Prioritize the Extraction Chest upgrade early to start banking valuable loot.
- The Metro Cart upgrade is highly valuable for experienced runners — it lets you skip lower difficulties entirely.
- At difficulty 5+, traps upgrade to active mines — bring high Perception or the Traps skill.
- If radiation is a problem, invest in the Auto-Doc tier 2 upgrade for rad cleansing between floors.
- The Extra Fob upgrade pays for itself over multiple runs.
- Graffiti tags for the MetroBlades quest are hidden on walls inside the tunnels — keep an eye out for them once you're on step 4 of the quest.
