The Bestiary26 CREATURES CATALOGUED

Enemies

Twenty-six catalogued creatures across five families. HP values and damage multipliers are community measurements, cross-checked against the 1.0 build — a multiplier above 1× means the creature takes extra damage; below 1× means your shots are mostly ceremonial.

Undead

Reanimated conquistadors — the jungle's rank and file. Most die to a single shot; the exceptions are listed with their multipliers.

CreatureHPDmg takenBehavior & tactics
Undead60Reanimated conquistadors, common near the beaches. One musket round drops them.
Berserk Undead20Fast and fragile — swings wildly, dies to anything.
Brute Undead1701.5×The tanky one. Takes extra damage, has the health to spare.
Hanged Undead180High HP but takes triple damage — aim carefully and it folds fast.
Lamp Undead60Carries its own light. You'll see it coming; it also sees you.
Lightning Undead60Electrical attacks.
Tue Tue Undead40Its shriek echoes across the whole forest and wakes everything. Avoid rather than fight.
Y'm-bhiFallen explorers reassembled as shambling dead — your own dead teammates can come back as these. Grabs crew members; a well-timed hit breaks the grab.

Otherworldly Horrors

Lovecraft's own menagerie, stitched in from across the mythos. Several of these cannot be killed at all — the HP column tells you which fights are actually fights.

CreatureHPDmg takenBehavior & tactics
Mi-Go60Mind control. Approaches from behind and separates prey from the group before it feeds.
Deep One1200.33×Amphibious and relentless, with heavy damage resistance — 120 HP that plays like 360.
Hound of Tindalos12010×Hunts whoever carries a moved treasure. Takes ten times normal damage — if you can land the shot before it lands on you.
Crawling Canopy180The tree-cover horror. Isolates and marks prey; about three musket rounds in the demo.
Prowler150Carries off lone explorers and cannot be killed — only driven back. Don't wander.
Flesh Shambler10000A territorial giant that displaces space itself. That HP number is the game telling you to run.
Formless SpawnShapeless and shapeshifting — spawn of Tsathoggua.
Haunter of the DarkLives in shadow. Keep your lamp lit.
Shoggoth WormA vast crawling mass.

Servants of K'n-yan

Agents of the underworld the expedition is digging toward. Both known servants take double damage — once you can tell them apart from your friends.

CreatureHPDmg takenBehavior & tactics
DoppelgangerInfiltrates disguised as a teammate and turns the crew against itself. Takes double damage once unmasked.
Transmuter120Bursts out of the ground under your feet.

Bosses

Named threats with no reliable numbers yet — still being measured in the 1.0 build. Treat every one as a run-ender.

CreatureHPDmg takenBehavior & tactics
Dark Young of Shub-NiggurathThe dark young of the Black Goat. Boss-tier; tactics still unmeasured pre-launch.
El Buey“The Ox.” Boss-tier.
The BoulderA moving hazard more than a fight.

Beasts

The jungle's mundane wildlife — mundane by local standards. One of them drains your sanity just by existing nearby.

CreatureHPDmg takenBehavior & tactics
HuemulA Chilean deer, and walking income: the meat sells for 80–120c and the hide for 60–90c.
BandurriaA daemon bird whose mere presence drains sanity. Shoot it from far away — 50 meters out is achievement range.
Tyrano HorseSpotted in the community codex; behavior undocumented.
WormySpotted in the community codex; behavior undocumented.

Reading the jungle

Enemy AI here doesn't charge. Creatures circle the crew, stalk at a distance and move through brush instead of open ground, so your first warning is usually movement in the leaves rather than a monster in your face. Three creatures deserve standing orders:

  • Tue Tue Undead — its shriek wakes the whole forest. Killing it loudly costs more than it saves; walk away.
  • Prowler — unkillable, and it takes people. It targets explorers who wander alone, which is the game telling you not to.
  • Hound of Tindalos — it hunts whoever carries a moved treasure, and it takes ten times normal damage. Decide before it arrives who the bait is and who shoots.

And the grimmest rule: dead teammates don't always stay on your side. A fallen explorer can return as a Y'm-bhi — so revive fast with Ammonia Salts, or haul the body to the ox-wagon before the jungle claims it.

How enemies detect you

Detection runs on two separate senses — sight and hearing — and the ranges are wildly uneven, which is the whole reason stealth works. The community codex measured several of them off the 1.0 build:

  • Prowler — sight just 8 m but hearing 18 m. It's functionally blind up close; noise is what draws it, so a lone, loud explorer is exactly its prey.
  • Deep One — sight 45 m, hearing 40 m, and it only takes 0.33× damage. Long eyes, thick hide: engage on your terms or not at all.
  • Crawling Canopy — sight 45 m. It reads as terrain until it moves, so that long sightline is easy to walk into blind.

The pattern for the rest of the bestiary is the same: keep noise discipline, break line of sight through brush, and never assume a creature that can't see you can't hear you. HP and damage multipliers above are demo-and-launch measured and re-checked against the community codex; we fill in the remaining sight/hearing ranges as they're confirmed.

Where to next

Bestiary questions

Which enemies can't be killed in The Mound?

The Prowler can only be driven back, never killed, and the Flesh Shambler's 10,000 HP makes it effectively unkillable — it's a territorial hazard to avoid. Boss HP is still being measured in the launch build.

What is the strongest enemy in the demo?

Of the measurable ones, the Deep One is the worst fight: 120 HP with a 0.33× damage multiplier, so it soaks roughly three times the bullets its health bar suggests — and it chases without giving up.

Why is a monster hunting only me?

If you picked up or moved a treasure, that's the Hound of Tindalos on your trail. It's extremely fragile (10× damage taken) if your crew is ready for it.
