Complete Horror Mutated Creatures and Threat Guide
Complete Horror mutated creatures are biological hostiles roaming the abandoned subway station, ranging from transformed transit staff to aggressive spiked beasts. Players must manage ammo, perform execution moves, and track protagonist infection to survive.

What Mutated Creatures Appear in the Subway?
Mutated creatures are hostile former humans and specialized entities altered by the outbreak across the transit tunnels. Exploration through the subway station brings contact with multiple distinct threat categories.
The game features both zombies and special mutated creatures. Each enemy type has unique behaviors and weaknesses, requiring different strategies to overcome. — the Steam store page
Standard mutated employees wander the corridors in search of targets. These workers retain humanoid frames but show severe physical decay and aggression, functioning alongside basic zombies. In close encounters, players can dispatch them with standard strikes or trigger high-damage execution moves when enemies become vulnerable.
Specialized mutations present higher physical dangers:
- Spiked Aberrations: In-game documents left by a survivor named Jim identify a mutated sector worker named Samuel, whose arms transformed into elongated spikes capable of impaling targets.
- The Tunnel Banshee: A giant creature roams collapsed sections of the line. This colossal entity pursues survivors through narrow passages, requiring rapid movement through structural gaps rather than direct weapon trades.
- Shadowless Apparitions: Notes scattered across the staff rooms mention entities without shadows that drift through restricted rooms alongside physical mutants.
The decision table outlines the operational response for handling major entity classes encountered underground:
| Encounter Type | Optimal Response | Tactical Trade-off |
|---|---|---|
| Mutated Employee | Engage with melee combat strikes and finish with execution animations | Conserves handgun ammunition but risks incoming physical damage in narrow spaces |
| Spiked Mutant | Keep distance and fire aimed pistol shots | Eliminates severe impalement danger quickly while consuming limited crafted rounds |
| Giant Tunnel Entity | Sprint through structural gaps toward environmental triggers | Bypasses unwinnable direct combat but demands fast route execution under pursuit |
How Does Protagonist Mutation Affect Survival?
Protagonist infection is a progressive biological condition that alters physical capabilities while threatening sudden death. Upon reaching Phase 3 genetic mutation in the station, an internal analyzer tracks contamination buildup as time advances.
Infection alters character attributes through specific trade-offs:
- Attack power and sprint speed increase as contamination accumulates across the infection gauge.
- Character appearance shifts as skin turns pale, cold, and blackened with visible contamination.
- Health depletes continuously once the mutation meter reaches maximum capacity, resulting in death if unaddressed.
Exposure to environmental threats like green gas accelerates contamination buildup. Survivors regulate this state using chemical items discovered in transit rooms. An orange anti-mutation compound lowers infection and restores small amounts of health, whereas a purple gene-altering catalyst raises contamination levels to temporarily boost physical performance. Stations equipped with automated analyzers allow players to stabilize cellular degeneration before tackling dangerous rooms.
Tactical Combat and Evasion Rules
Defeating subway hostiles requires strict inventory control. Information provided on the Steam store page notes that ammunition and restorative resources remain limited throughout every sector. Patch notes on the Steam community also highlight ongoing tuning for combat balance and item interactions.
Firearms provide critical range against dangerous opponents. Players find a handgun inside the station security office, but reserve magazines depend entirely on collected resources like gunpowder and empty casings gathered from maintenance rooms. Melee weapons, including the craftable axe and combat dagger, handle isolated mutated employees without burning gunpowder supplies.
When facing larger mutated specimens or clusters of infected staff, evasion offers the safest outcome. Crouching silences footstep audio and allows passage beneath low obstacles, keeping the character outside enemy alert radiuses. Conserving ammunition for mandatory encounters ensures sufficient firepower remains available when blocked by durable monstrosities deeper in the facility.
