Parasite in City: Nightwalkers is an unofficial, non-commercial fan project by Ms Niche, made in Unity 2022 as another chapter in the Parasite in City legacy. It preserves the original sprites, sounds, atmosphere, and identity while adding new enemies, two more weapons, redesigned controls, and fresh systems and encounters. You play a female protagonist in a short, focused sprite-based shooter set in the familiar city world, with pregnancy among its themes.
The current v1.05 build is dated September 7, 2026, and was released September 8, 2026, so development is ongoing. It runs on Windows in English and is uncensored. The latest update reworked the camera to match the original more closely, added Normal, Hard, and Nightmare difficulty modes, broad gamepad support, and resizable windowed mode with Alt+Enter. It also adjusted zombie and bug behavior, reduced Molotov distance and shotgun volume, and added Pregnancy to the Gallery.
Developer's description
Parasite in City: Nightwalkers
is an unofficial, completely non-commercial fan project created as a new chapter in the legacy of
Parasite in City
.
Built in Unity 2022 while preserving the original game’s sprites, sounds, atmosphere, and identity, Nightwalkers expands on that foundation with new enemies, two additional weapons, redesigned and more intuitive controls, and a range of new gameplay systems and encounters.
This is a short, focused experience by design—not an attempt to turn
Parasite in City
into something it was never meant to be.
The goal is simply to recapture what made the original memorable, give longtime fans a reason to step back into its world, and show what another chapter could look like.
Short and sweet, familiar but new, Nightwalkers is meant to be a new beginning.

v1.04
September 2nd, 2026
Grab escapes redesigned:Grabbed players now escape by holding the displayed key until the bar fills. Progress pauses when released and resumes when held again. There is no time limit, progress decay, wrong-input penalty, or damage for failing to escape.
WASD controls use Spacebar by default.
Arrow Key controls use Z by default.
Rebinding is supported.
Dialogue now freezes gameplay: Enemies, projectiles, hazards, and encounter progression are paused while dialogue is active, then resume normally afterward.
Flying bug dives are more predictable: Flying bugs now attack beside the player instead of directly on top of them, making their approach easier to read and giving you a clearer direction to evade.
Stage 1 melee tutorial added: The opening encounter now displays a melee prompt shortly after gameplay begins. It completes when a Zombie Grunt is killed using melee.
Main Menu music volume control added: You can now adjust menu music volume directly from the Main Menu alongside the mute control. The setting is shared with Options and persists between sessions.
v1.03
September 1, 2026
Significant balance adjustments across Stage 1 and Stage 1B, including more ammunition and fewer enemies. Balance is still ongoing and may continue to change based on majority player feedback.
Lightning Flash can now be toggled ON or OFF from the Accessibility tab in the Options menu.
Added two display scaling modes:
Fit Screen
for better use of higher-resolution displays, and
Pixel Perfect
for a crisper original pixel presentation, particularly around 1080p and below.
Updated the Game Over screen and Control Scheme background presentation.
v1.02
August 30, 2026
Fixed startup and loading black-screen issues affecting some older-generation computers
, including improved video compatibility and more reliable transitions into Stage 1.
Fixed QTEs disappearing after pausing and unpausing.
Adjusted Zombie Grunt and Zombie Dog QTE positioning
so prompts appear in better positions during grabs.
Fixed the THROW prompt appearing too far left and partially out of bounds
; it now aligns correctly and sits above the player’s head.
Fixed the RELOAD prompt’s positioning and presentation
; it now sits above the player’s head and uses the same black backdrop as THROW.
v1.01 — Hotfix
August 29, 2026
Game Over audio now becomes muffled and distant instead of cutting to complete silence.
Fixed the player using the shotgun animation after escaping a grab while holding the pistol.
Added laptop and smaller-screen support, preventing the game from being cut off on resolutions such as
1366×768
and
1280×720
.

Nice job, its a really interesting project. making it in unity also brings addons to the table so i think it was a good call. thanks for your hard work i'll continue to follow on the next updates. I kind…
Tusk2026-09-10★★★★★
It's definitely got potential for a fan game, but it just misses the feel. There's no jumping, no low-kick, no physics objects like the crates in the first game, flies behave too differently, crouching is awkward, masturbate button is missing…

Sadly I can't rate this any higher than a 2 star as of 1.05. It certainly feels better than I expected given prior reviews, but it still has a ways to go in its fundamental design and execution of said…
