Which arenas exist?
Public materials and Steam history list multiple arenas. Treat Early Access “two maps only” posts as outdated.
| Arena | Notes |
|---|---|
| Isolated City | Starter arena; Huntress 15-minute unlock goal |
| Vile Wasteland | Desert hazards; worm; Sanji often discussed here (community) |
| Dead Terminal | Later arena; gates Bio Lab Default clear in public notes |
| Bio Lab | 1.0 arena; unlock after Dead Terminal Default |
| Others / variants | Confirm in-game list after patches — TBA names welcome |
Why the list grows
1.0 explicitly adds Bio Lab. Older wiki pages may lag — prefer Steam/in-game unlock text.
Sanji note
Potato/Sanji window POIs are community achievement reports, not an official compass marker. Details: potato.
How do I unlock later maps?
Maps and modes interlock. Public achievement-style gates historically include surviving set times, clearing Endless/Hardcore style goals, and finishing prior arenas.
| Target | Public gate note |
|---|---|
| Vile Wasteland | Survive long enough / clear prior goals (verify live) |
| Hardcore | Historically tied to long Endless-style survival achievements |
| Boss Rush | After Hardcore clears (per-map notes in 1.0 talk) |
| Bio Lab | Complete Dead Terminal Default |
| One Hit | Often gated behind Boss Rush style clears — verify |
Do not skip Default
Default clears teach layouts before Hardcore modifiers spike enemy speed and damage.
What hazards should I respect?
Each arena adds enemies and environmental threats beyond Isolated City spitters.
| Arena cue | Hazard focus |
|---|---|
| Isolated City | Learn basic spitters and elite telegraphs |
| Vile Wasteland | Desert worm, mummies/scarabs, slime packs |
| Dead Terminal | Terminal layout chokes — avoid dead corners |
| Bio Lab | Lab sightlines; treat as late-game literacy |
| Sanji windows | Achievement POI (community) — see potato page |
Movement still wins
Auto-fire does not dodge for you. Wide kiting lanes matter more on worm maps than on open city blocks. Log the telegraph that killed you after each wipe so the next Default attempt teaches a concrete hazard instead of a vague 'this map is hard' feeling.

How do modes use these maps?
Modes reuse arenas with different rules.
| Mode | Map note |
|---|---|
| Default | Primary unlock and learning mode |
| Hardcore | Higher pressure on same arenas |
| Boss Rush | Compressed Boss focus after Hardcore gates |
| Endurance / Extermination | Wave or timed elite pressure variants |
| Infinite | Relaxed item limits; many achievements off |
| One Hit | Precision mode — unlock gated |
Torments
1.0 lists 28 Torments — modifiers that can invert map difficulty. Exact list TBA on a future modes page.

How do I learn a new arena safely?
Learning Yet Another Zombie Survivors maps means one hazard literacy goal per night. Clear Default, note choke points, then decide whether Hardcore is earned.
| Focus | Detail | Next action |
|---|---|---|
| Isolated City | Spitters + basic elites | Unlock Huntress time goal |
| Vile Wasteland | Worm + desert packs | Potato/Sanji awareness |
| Dead Terminal | Choke discipline | Gate Bio Lab Default clear |
| Bio Lab | Late sightlines | Do not jump in cold |
| Hardcore promote | Same map, less greed | Sustain chests |
| Boss Rush gate | Hardcore clears first | Verify per-map rules |
- Do01Confirm unlocks and mode gates before forcing a plan
- Do02Lead when Rank or full perk is required
- Do03Rescue only on safe beacons
- Do04Match chests to tags already on the squad
- Do05Keep unverified math as TBA
Hazard notebook
Write one sentence after each wipe: which telegraph killed you. Map knowledge compounds faster than random Training damage nodes. Sanji hunters should still read potato before dedicating a Wasteland night.

Unlock chain checklist above is the spine. Training for tougher arenas: upgrades. Trophy gates: achievements.
How do I notebook arena hazards?
Keep a Yet Another Zombie Survivors maps hazard notebook with one kill-cause sentence per wipe. “Worm telegraph while chest greeding” is actionable; “map is unfair” is not.
Unlock order still matters: City literacy, Wasteland worms, Terminal chokes, Bio Lab late sightlines. Skipping Default on a new arena to “save time” usually costs more wipes than it saves.
| Situation | Do this | Avoid |
|---|---|---|
| New arena | Default first | Hardcore cold start |
| Repeated wipe | Log telegraph | Blind Training dump |
| Bio Lab locked | Clear Dead Terminal Default | Random forum myths |
| Boss Rush locked | Finish Hardcore gates | Forcing the mode early |
| Sanji night | Potato page first | Aimless window camping |
FAQ
Where is Sanji?
Village/houses windows after Potato stacks — potato.
Is Boss Rush a map?
It is a mode that uses arena Boss content after Hardcore gates.
Are old “two maps” guides correct?
No — outdated Early Access snapshots.
How many maps are there after 1.0?
At least Isolated City, Vile Wasteland, Dead Terminal, and Bio Lab in public materials, with mode variants on top. Prefer the in-game list over Early Access 'two maps' posts.
Is Boss Rush required for Bio Lab?
Public notes unlock Bio Lab by clearing Dead Terminal Default. Boss Rush is a separate Hardcore-gated mode. Do not conflate the two gates.
Where do desert worms show up?
Vile Wasteland discussions highlight desert worm hazards alongside mummy and scarab style packs. Learn Default telegraphs before Hardcore on that arena.
