Introduction

The Enemies hub is your field guide to the eldritch threats that stalk flooded Arkham in The Sinking City 2. Survival horror is defined by its adversaries, and Frogwares has drawn on the Cthulhu Mythos to populate the drowned city with creatures that demand respect — The Slither animating the dead, Deep Ones surging from dark water, and Shadows that bend space and disorient the eye. Understanding how each enemy behaves, what it is weak to, and when you should simply run is the difference between a smooth expedition and a wasted trip back to the last safe point. This category ranks the threats, explains their attack patterns, and gives you a clear decision framework for when to fight, flee, or rearm before returning better prepared.

Threat Roster

S

Eldritch Horrors

Boss-tier horrors and empowered entities that demand your full resource budget to defeat.

BehaviorSlow, deliberate, and devastating. They soak up damage and punish rushed play, so the fight is as much about patience as firepower.
Best StrategyCommit your full arsenal, hold a clear retreat line, and if resources run low, retreat, rearm, and return rather than dying mid-fight.
A

Deep Ones

Fast, flanking amphibious stalkers that surge from dark water and test your positioning.

BehaviorThey use the flooded streets as cover, flank aggressively, and close distance quickly, punishing players who stand still.
Best StrategyPick high ground, keep an escape route open, and commit heavy firepower at close range when they commit to the attack.
B

The Slither

The undead animator — a mid-tier threat that turns dead bodies into pressing swarms.

BehaviorIt reanimates corpses into clusters that press from multiple angles, trying to surround you in enclosed spaces.
Best StrategyUse a shotgun at close range to shred the swarm before it closes in, and finish staggered corpses with melee to save ammo.
C

Shadows

Space-bending entities that disorient the eye — more hazard than kill target.

BehaviorThey warp space around themselves, making distance and direction hard to read, which can panic unprepared players.
Best StrategyIgnore them, reposition, and break line of sight rather than wasting ammunition — they are avoidable once you know their tells.

Core Mechanics

Enemy design in The Sinking City 2 follows the classic survival horror philosophy: every creature is a problem to be solved with resources you do not have enough of. The Slither manipulates corpses, turning dead bodies into swarms that press you from multiple angles — the shotgun is the reliable answer, shredding clusters before they surround you. Deep Ones are amphibious stalkers that surge from dark water and flank aggressively, so the best counter is a clear escape route and heavy firepower committed at the right moment rather than panic fire. Shadows bend space and disorient the eye, but they are more avoidable than deadly once you understand their behavior — reposition and break line of sight rather than wasting ammunition. Boss-tier eldritch horrors demand your full resource budget or an honest retreat. The game is explicit about this: some fights are meant to be fled, rearmed for, and revisited later.

Advantages

Learning your enemies is the highest-value knowledge in The Sinking City 2 because it converts scarce ammunition into reliable kills. When you know that The Slither swarms are best shredded by a shotgun at close range, you stop wasting pistol rounds on moving targets and start clearing rooms efficiently. When you recognize Deep Ones as flankers that surge from water, you learn to control distance and pick your ground instead of being surprised every time. When you understand that Shadows are more disorienting than deadly, you stop burning ammunition on them entirely and simply reposition. A player who reads the threat board knows exactly which fights to take, which to slip past, and which to run from — and that judgement is what turns a resource-lean survival horror into a manageable one.

Challenges

The enemy roster of The Sinking City 2 punishes overconfidence, and no guide can fully prepare you for the moment a Deep One flank surprises you mid-loot. Some fights are designed to be unwinnable on a first visit — the game expects you to retreat, rearm, and return, which can feel frustrating if you are used to pushing through every encounter. Ammunition pressure means you cannot simply shoot your way past problems, and the more aggressive creatures, especially the boss-tier eldritch horrors, demand resources you may not have. Enemy behavior may also evolve with the flood and with difficulty settings, so a tactic that works early may need adjusting later. Our guides give you the framework, but survival still comes down to your own judgement in the moment.

FAQ

How do I beat The Slither?+
The Slither is the enemy that animates the dead, turning corpses into pressing swarms that try to surround you. The most reliable counter is close-range firepower — a shotgun shreds clusters of the undead before they close in. Try to engage them in a choke point or open space where you control the angles, and avoid letting them pin you in a corner. Conserve your pistol and SMG ammunition for other threats; the shotgun is the tool for this fight, and a melee finish on a staggered corpse costs nothing at all.
How do I deal with Deep Ones?+
Deep Ones are fast, amphibious stalkers that surge from dark water and flank aggressively. The key is controlling the engagement: fight them on your terms, never in water you cannot see through, and always keep a clear escape route. Commit heavy firepower when they commit — panicked fire just burns ammunition. If a Deep One group is too large or too fast, retreat, rearm, and return with more firepower. These fights reward patience far more than they reward aggression.
Are Shadows worth fighting?+
Usually not. Shadows bend space and disorient the eye, which makes them more of a hazard than a kill target. Once you recognize their behavior, the smart play is to ignore them, reposition, and break line of sight rather than waste scarce ammunition. If a Shadow is blocking your route, a burst of fire to create space and then a quick escape beats a prolonged engagement almost every time. Save your resources for the fights that actually matter.

Quick Tips

💡

Learn to read a room before you enter it. If you see dark water ahead, assume Deep Ones are waiting and plan your engagement ground with an escape route behind you — the fights you win clean are the fights you set up in advance. Understanding a creature's behavior is worth more than any single weapon upgrade, because it lets you solve encounters with positioning instead of bullets.

💡

Let the shotgun earn its keep against The Slither. Clusters of reanimated corpses fold fast to close-range pellets, and a melee finisher on a staggered enemy costs nothing — this combination clears rooms while barely touching your pistol ammunition. The game rewards players who treat every engagement as a decision rather than a reflex, and the extra second you spend reading the room is the second that saves the fight.

💡

Treat retreat as a strategy, not a failure. When an encounter is burning your resources faster than it should, back out, rearm, and return. The game is designed around players who know when to fight and when to save their strength for a better position. Fighting on your terms, with an escape route and the right tool for the threat, turns the game's most terrifying encounters into manageable problems.

💡

Boss-tier horrors are resource checks, not reaction tests. Before engaging, count your ammunition, healing, and escape route. If any one of the three is missing, the correct play is to leave and come back properly prepared. The horror is real, but the threat assessment is what keeps you alive; calm players who classify every enemy by threat level and counter rarely waste resources.
