Residence Massacre Undeads — Stalker Horde

Undead Enemies Explained — Residence Massacre

Undeads are the reanimated corpses that follow The Stalker during Night 2. They are not a separate anomaly class — they are the horde that Stalker summons when its audio cue finishes. This page covers spawn triggers, the three Undead variants (Crawler, Wailer, Shambler), how they behave differently from Husk and Pest at door barricades, and the dawn-despawn rule that ends every Night 2 with a clean wipe.

What Undeads are

Undeads are corpse-like Robloxians with pale green skin, tattered clothing, and missing limbs (always the left arm in the same rig). They walk slowly when first spawned but accelerate to a shambling jog after 8 seconds if they have not engaged a barricade. They do not have guns. They do not have flashlights. They are pure melee.

Key stats from the August 2026 build:

• HP per Undead: 30 (one hammer hit drops them to zero).
• Damage per hit: 15 (one hammer hit from them on a player).
• Walk speed: 4 studs/sec (first 8 seconds).
• Run speed: 7 studs/sec (after 8 seconds).
• Aggro radius: 12 studs.
• Door interaction: break a single plank in 1.4 seconds.

The Undeads are the only anomaly class in Residence Massacre that stacks — multiple Undeads can attack the same barricade simultaneously. A barricade with 4 Undeads on it loses all 4 planks in 3.5 seconds, faster than any single-anomaly attack in the game.

Where Undeads spawn

Undeads do not spawn on their own. They spawn only as a follow-up to The Stalker audio cue. The exact trigger:

1. Stalker audio cue plays — a low, sustained hum layered over wind ambience. This is the “stalker is approaching” cue.
2. Cue ends — silence for 2 seconds.
3. Undead spawn — 1–4 Undeads appear at a random point in the forest ring around the residence. Spawn point is invisible to the player until the audio cue is replaced by footsteps on dirt.

Total Undead spawn count in a Night 2 clear depends on night length and player performance:

Performance	Total Undeads spawned
Optimal (no wipes)	12–16
Average	18–24
Sloppy (multiple breaches)	28–35
Worst recorded clear	41

The worst-recorded clear was logged on the Miraheze community wiki from a December 2025 run by player NatureViking.

The three Undead variants

Tea Studio ships three visually distinct Undead variants. They share the same HP, damage, and aggro radius, but differ in spawn rules and special abilities:

Crawler

The most common variant. Crawlers are Undeads with both legs broken — they shamble on their knees at half speed but do not trigger door audio. They are the silent variant.

• Spawn rate: 70% of all Undeads.
• Speed: 3.5 studs/sec (always half speed).
• Door interaction: yes, same as standard.
• Audio cue: none (this is their defining trait).

Crawlers are why audio discipline matters in Night 2. The Stalker cue plays once per spawn wave, but Crawlers can appear without a new cue if the wave has multiple variants.

Wailer

A Undead with a missing jaw. Wailers emit a sustained wail every 4 seconds. The wail stuns the closest player for 0.6 seconds if the player is within 8 studs and looking at the Wailer.

• Spawn rate: 20% of all Undeads.
• Speed: 7 studs/sec (always run speed).
• Door interaction: yes.
• Audio cue: wail every 4 seconds.

The Wailer stun is a critical mechanic in co-op because a stunned player cannot call out Stalker positions. Pub lobbies that ignore Wailers get wiped at the door when two teammates are stunned simultaneously.

Shambler

The largest variant. Shamblers have both arms intact and use them to bash rather than scratch. Each bash does 30 damage (double standard) and breaks 2 planks at once.

• Spawn rate: 10% of all Undeads.
• Speed: 5 studs/sec (slow walk, never runs).
• Door interaction: yes, double plank loss.
• Audio cue: heavy footsteps.

Shamblers are the rarest variant. A 30-Undead clear typically has 3 Shamblers. Pub lobbies that prep 8+ planks at the front door handle Shamblers cleanly — one Shambler bashes through 4 planks in 2 seconds, but 8+ planks absorbs two Shamblers before the hammer player can reset.

How Undeads differ from other anomalies

It is easy to confuse Undeads with Husk (Night 3) or Pest (Night 1 windows). Key differences:

Feature	Undeads (Night 2)	Husk (Night 3)	Pest (Night 1 windows)
HP	30	200	50
Door damage	1.4s per plank	3s per plank	2s per plank
Aggro radius	12 studs	20 studs	15 studs
Spawn trigger	Stalker audio cue	Worker mutation event	Window light off
Daytime behavior	Vanish	Continues	Continues
Audio cue	Hum + footsteps (Crawler: silent)	Cough + groan	Phase whine

The biggest functional difference is vanish at dawn. Undeads despawn the moment the sun rises at 6 AM. Husk and Pest continue hunting until the night timer ends (also 6 AM, but they have a 30-second linger window during which they can still attack).

Why Undeads vanish at dawn

The lore reason is that the radioactive spill at the Robloxia Factory (see Soldiers for the news bulletin) is UV-reactive. The spill that reanimated the corpses cannot survive direct sunlight. Husk and Pest are different biological processes — Husk is a Worker mutation event, Pest is a spiritual entity — so they continue past dawn.

The mechanical reason is balance: Night 2 ends with a sunrise cutscene showing the Player driving away. If Undeads continued to chase, the cutscene could not play. Tea Studio chose lore-accurate despawn over gameplay convenience.

Co-op etiquette and Undead priority

In a four-player Night 2 run, Undeads are a hammer player problem first:

1. Hammer — primary Undead counter. Each Undead takes one hammer hit. Hammer player should stay near the front door and call “undead door” before planks pop.
2. Caller — watches Stalker audio cue and announces when Undeads will spawn.
3. Power — fuels during the lull between waves. Power should not engage Undeads.
4. Runner — collects dropped planks from dead Undeads (they do not drop planks, this was a 2024 myth — see FAQ).

The standard rule: Caller never hammers. Caller watches Stalker audio and is the only person who can announce the next wave timing. If the Caller also hammers, the team misses the audio cue and gets wiped by Crawlers.

What Undeads are not

• Not Husk. Husk is a single anomaly in Night 3, not a horde.
• Not Pest. Pest is a spiritual window-attacker in Night 1.
• Not Abomination. Abomination is a Bunker-only boss.
• Not in Night 1 / Night 3. Undeads only spawn in Night 2.
• Not in Endless. Endless mode has its own anomaly roster (Crawler variants, Robot variants), not Undeads.
• Not in the Memories. Memories use a different spawn script that does not include Undeads.
• Not in PvP. PvP was temporarily removed on January 9, 2026. Undeads were never in PvP.
• Not buyable in the Coins Shop. No gamepass, no Coins Shop item unlocks Undeads.
• Not affected by gamepasses. Better Flashlight does not improve Undead detection. Iron Lungs does not affect Undeads because Undeads do not have a chase-breath mechanic.

Patch history

Date	Patch	Change
October 2023	Launch	Undeads first appear in Night 2 alpha
August 2024	Quality of Life 2024	Crawler variant added (silent Undead)
January 2025	QoL 2025	Wailer stun duration raised from 0.4s to 0.6s
April 19, 2026	April Fools 2026	Shambler plank-bash damage capped at 30 (was 50)
January 9, 2026	PvP removal	Undead drop-on-death plank myth officially debunked in patch notes
August 21, 2026	Night 1 Rework	Night 2 spawn wave cap raised to 41 (was 32)

The current meta is 8+ planks staged for any Night 2 clear, with the hammer player assigned to front door exclusively. Solo Night 2 with one Undead spawn wave every 6 minutes is a known difficulty curve that the August 2026 patch did not change.

Voice, sound, and small details

• Undeads have no voice lines. They are silent NPCs with only ambient audio (footsteps, wail, breath).
• The Crawler’s silence is intentional — players who rely on audio to spot Undeads will miss Crawlers entirely. Pair with Camera Setup.
• The Wailer’s wail audio is the same sound effect used for the Night 1 Pest whine at half pitch. Tea Studio’s audio team reuses the sample at lower pitches for horror effect.
• The Shambler’s bashing audio is a single impact sound — three Shamblers bashing simultaneously sound like one Shambler. Do not count audio to identify Shambler count.
• Undead bodies do not stay on the ground after death. They despawn 0.5 seconds after being hammered. This is what created the 2024 “Undeads drop planks” myth — players thought the despawn flash was a plank pickup animation.

Common Undead mistakes

• Caller hammering. Caller must stay on monitors and announce Stalker audio. If Caller also hammers, the team misses Crawlers.
• Ignoring Wailers. Wailer stuns stack. Two simultaneous stuns = a wipe. Hammer Wailers first, even at the cost of leaving one Crawler on the door.
• Spending planks on Crawlers. Crawlers are 1.4s per plank. If you have 6 Undeads on the door, drop 6 planks — do not retreat to repair one plank at a time.
• Fighting at night end. Night 2 ends with a sunrise cutscene. Do not waste planks on Undeads at 5:55 AM — they will vanish in 5 minutes anyway. Stage planks for the next night.
• Solo Night 2 with no Caller. Solo Night 2 has no cameras. You must listen to audio only. If you cannot tell Crawler from Wailer from Shambler by audio, solo Night 2 is not for you.

Undeads are Residence Massacre’s horde anomaly — a Stalker-summoned wave of corpses that pressure Night 2 barricades. Listen for the audio cue, hammer Wailers first, drop planks on Crawlers, and survive until sunrise. The dawn cutscene does the rest.
