HUSH [Zombie Extraction] is a co-op extraction game from Blue Code Studios. You drop into the quarantined town of Stillwater, loot what you can, and leave through an exit before the raid timer runs out. The infected are blind, but they hear everything. Every gunshot, smashed window or sprint tells them where you are. The game is pure PvE and in open beta, so systems and numbers can still shift between updates.
Quick answer: Pick an exit you can qualify for before you loot, kill lone infected with melee, and extract before the 20-minute timer ends. If you die, only your secure container comes home.
You can launch the game from its official Roblox page.
HUSH raid rules: Death, timer and squads
Every raid works on one bargain. Whatever you carry in is at risk. If you die before extracting, the “KILLED IN ACTION” screen wipes everything except the items inside your secure container, which some players call the secure case or pouch. Put your most valuable find in it as soon as you pick it up, and never deploy with gear you can’t afford to lose.
- A Stillwater raid lasts 20 minutes.
- You can play solo or bring up to three friends, for a four-person squad.
- A Stillwater raid holds 12 survivors in total. Other players are never hostile.
- On Stillwater Normal, you have 30 seconds to revive a downed teammate.
- A PvPvE mode is planned, but no release date has been confirmed.
You can invite friends from the bar at the top of the PLAY screen, or use Find squad — PUBLIC to join strangers. There are two maps: Stillwater, and the underground Hollow.
Difficulty tiers and time of day
| Difficulty | What changes | Unlock |
|---|---|---|
| NORMAL | Baseline for learning | Open |
| HARD | More infected, moving faster | Open |
| NIGHTMARE | Night only, fast bites | Doc’s Patient Zero task |
Time of day can be set to DAY, DUSK or NIGHT. ANY picks one at random. Higher tiers pay out better, so they’re worth it once you know how loud your own habits are.
First Stillwater raid walkthrough
New accounts start with $5,000. Your first deployment is a six-step tutorial set in a single suburban house. It covers every core action in the game, so it’s worth playing all the way through.
A successful extract ends on the raid report. The tutorial run shows 1 kill, +20 EXP and a loot value of $5,000. If that screen appears, everything you carried is now in your stash.
Back in the lobby, hand in Doc’s “FIRST RESPONSE” task. Its only objective is to extract from one raid. It pays $1,500, +40 REP, two Bandages and Painkillers.
| Item | Type | Weight | Sells for |
|---|---|---|---|
| Pager | Valuables | 0.2 kg | $275 |
| Crowbar | Melee (11 damage) | 1.8 kg | $410 |
| P17 Pistol | Handgun | 0.7 kg | $1,600 |
| Car Battery | Materials | 13.5 kg | $5,120 |
Weight matters. Heavy items like the battery drain stamina and slow you down until your Strength skill rises. When your bags fill up, drop low-value filler such as empty bottles or plain water to make room for items that sell well.
HUSH extraction points and requirements
Press M to open the map. Your position is a blue dot, and squadmates appear as ringed dots in different colors. Click an exit to ping it for your squad, or click empty ground to place a shared waypoint. Each exit has its own condition, so check yours early in the raid.
Stillwater exits
| Exit | Location | Requirement |
|---|---|---|
| Highway Roadblock | West, Route 9 | Always open |
| Hospital Helipad | Southeast, Hospital | Light a flare on the pad |
| Smuggler’s Boat | East, by the river | Pay $2,000 cash |
| Gas Station Pickup | — | Car battery + fuel can |
| Storm Drain | — | No backpack |
| Military Gate | — | Listed exit |
| Garden Gate | Tutorial house | Stand in beacon |
To use Highway Roadblock, step into the yellow-marked area between the two police cars, near the sandbags and the EXIT sign, and stay put until EXTRACTING completes. The helipad flare only works if you light it on the pad itself.
When “THE PICKUP TRUCK HAS LEFT” appears, Gas Station Pickup is closed for the rest of the raid.
The Hollow exits
The Hollow’s Site Map has multiple floors. Switch between them with Q/E or the floor tabs. The Sinkhole, Archive Stacks, Security HQ and the Underground River are the landmarks to orient by.
| Exit | Requirement |
|---|---|
| Sinkhole Switchback | Always open |
| Vent Raise Ladder | Backpack of 9 cells or fewer, one person at a time |
| Rook’s Raft | 2,500 Cash from your stash |
| Director’s Escape Tunnel | Black Card |
The Vent Raise Ladder limit applies to how big your backpack is, not how full it is. To use Rook’s Raft, follow the indicator through The Caves to the dock, choose “Pay the smuggler,” and wait out the countdown. A Staff Card opens Security HQ. Other Hollow exits need a fuel can or generator power.
Noise, infected types and raid events
An audio and visibility meter sits in the bottom-left of the HUD. It reads SILENT, LOW or AUDIBLE. Crouching keeps footsteps quiet. Unsuppressed gunfire pulls in a swarm fast, and a long indoor firefight can end with a horde pinning you against the furniture. Shoot only when you’re close to an exit or have no other way out.
Closing a door behind you breaks line of sight and buys time during a chase. If the door won’t shut, step out of the doorway first. Windows offer three separate actions, Smash Window, Clear glass and Climb through, so check which one is selected before you press F.
| Infected | Trait |
|---|---|
| Walkers | Basic infected |
| Runners, Brutes, Screamers | Named special types |
| Listeners | Blind |
| Ringers | Carry pagers |
| Riot cops | Carry shields |
| Crawlers | Count toward a Ward C task |
There are five bosses. The Chief guards Security HQ in The Hollow and wears a dark uniform with a white cap. The Mayor wears a red suit, can sprint and has sharp hearing. If “She heard you” appears on screen, she’s heading straight for you.
Helicopter rotor noise draws infected along the flight path. When the AIR TRAFFIC notice appears, treat it as a noise warning and rethink your route. It is not a helipad or airdrop signal. Airdrops are a separate event and can drop backpacks and armor. Some raids also roll modifiers.
- SURPLUS adds extra supply airdrops.
- BLACKOUT turns the lights off.
- LOUD NIGHT makes noise louder.
- OUTBREAK adds more infected.
Bleeding, infection and stamina cures
| Condition | Sign | Cure |
|---|---|---|
| Bleeding | Red outline, steady HP loss | Bandage |
| Low health | Critical HP | Pills / Painkillers |
| Infection | Blurred screen edges, countdown | Antiviral |
| Low stamina | Sprint runs out | Cold Cola |
Stop the bleeding first, then heal. To use an item, right-click it and choose Use, or press E when a quick-use prompt appears. Stopping bleeding does nothing for an infection. If the infection countdown runs out, you turn and die. Antiviral comes in green-and-white packaging with an ANTIVIRAL quickbar label. Splints also treat injuries. Cola cuts stamina use while sprinting by 40% for three minutes, which is tracked by the ENERGY RUSH timer, and drinking another can resets that timer. Residential medicine cabinets and desks are the best places to look for medical supplies.
Loot, inventory grids and weapons
Your storage is a grid, and every item takes up a set shape. The Rifleman Rig offers 12 cells (4×3) and the Hiking Backpack offers 20 cells (4×5). A School Backpack can turn up mid-raid. Armor such as the Scrap Vest, Courier Rig and Riot Leg Guards have their own protection values, including bite resistance, so you’re often trading carry space for defense.
- Wardrobes can hold equipment, Scrap and Rags.
- Cabinets can hold Scrap, Toolkit and Tape.
- Red landmark names on the map mark areas with more loot.
- Checkpoint, in northeast Stillwater, has lockers, desks, safes and weapon crates.
- Town Hall can give a Safe Key or Mayor’s Key, and office desks are worth checking for keys too.
You can carry one primary and one secondary firearm, plus a melee tool in slot 3. Headshots deal roughly three times normal damage. Torso hits deal standard damage, and arm or leg hits deal about 60–70%. The Gunner sells FMJ, AP and HP ammo. Electronics such as computers can sell for around $6,000, so check an item’s value before you drop it.
HUSH traders, prices and the Gunsmith unlock
Between raids, you buy, sell and pick up jobs from the traders. Doc (Dr. Nadia Grover, Recovery Clinic, Route 9) sells medical supplies. Gunner (Walt Brookham, Grain Silo, North Fields) sells weapons, ammo, armor and attachments. Scrapper (Sal, Old Gas Station, Red Valley) sells tools, backpacks, crafting parts and keys that open map-specific rooms and vaults.
| Trader | Item | Price |
|---|---|---|
| Doc | Bandage | $110 |
| Doc | Bottled Water | $170 |
| Doc | Splint | $340 |
| Doc | Painkillers | $410 |
| Doc | First Aid Kit | $1,700 |
| Doc | Trauma Pack | $3,200 |
| Doc | Antiviral Capsules | $10,000 |
| Gunner | STARTER KIT | $1,000 |
| Gunner | P17 Pistol | $3,200 |
| Gunner | Soft Armor Vest | $4,000 |
| Gunner | M1911 Pistol | $4,300 |
| Gunner | .357 Revolver | $5,800 |
| Gunner | M87 Pump | $6,800 |
| Gunner | Bolt-Action Hunting Rifle | $9,400 |
| Gunner | MK5 SMG | $14,800 |
| Gunner | CB-S Short Carbine | $19,400 |
The STARTER KIT includes a P17 Pistol, one 9x19mm FMJ and a Bayonet. At $1,000, it’s the cheapest way to get a gun and a melee weapon into your first few raids.
The Gunsmith, who handles advanced weapon crafting and customization, starts out locked. To unlock her, finish Gunner’s “MORE” task (after reaching Gunner level 2 and completing DINNER BELL), Doc’s “HER SCRAP” task, and a Scrapper quest.
Tasks and rewards
Tasks pay cash, reputation, gear and keys. Scrapper’s SALVAGE RIGHTS asks you to hand over two scrap metal and two wires, all found in raid. It pays $2,500, +8 REP, a Toolbox and the Pharmacy Back Room Key. Other tasks include Crane’s Logs, Smuggler’s Deal, Cold Chain, Ward C, Quiet Work, Buddy System and The Shriek. Some tasks are timed. SALVAGE RIGHTS, for example, shows a days-remaining counter.
Blackmarket, skills and hideout
The Blackmarket lists weapons and crates put up by other players. Crates open into cosmetic weapon skins. Field Case listings start at $50,000, Tarot Case and Vault Case at $60,000, and Halloween 2024 Case at $7,000,000.
Skills level up on their own the longer you survive in raids. Aim tightens spread, Reload speeds up magazine changes, Sneak quiets footsteps, Endurance extends sprinting, and Strength raises how much you can carry before slowing down. First Aid speeds up treatment and revives, Looting widens loot detection and adds a small chance of a bonus find, and Melee makes hits harder.
The underground hideout has upgrade stations: a Generator, Workbench, Shooting Range and Med Station. Other menus include Collection (gear and infected profiles), Badges (Survival, Combat, Hideout and Story), weekly and all-time leaderboards, a Faction War between Doc, Gunner and Rook, and a Store selling kits, currency, stash expansions and VIP perks.

HUSH Zombie Extraction codes
No working codes are confirmed right now. The code HUSH4K has been circulating, but it doesn’t redeem. Codes are entered in the code redemption section near the bottom of the Settings menu. A valid code gives you its reward as soon as you confirm it, so if nothing arrives, the code isn’t live. Don’t use auto-loot scripts that claim to work in beta games either. They put your Roblox account at risk.
