NightCoop - Cyberpunk 2077 Co-op Mod: Download & Install Guide

ⓘ

Short version: download the build your group agreed on, unzip the whole archive into your Cyberpunk 2077 folder (it bundles RED4ext 1.30 — nothing else to install), launch the game and a "Co-op" item appears in the main menu. Host opens a session, guests join by code.

⚠

Before anything: back up your saves at %USERPROFILE%\Saved Games\CD Projekt Red\Cyberpunk 2077. NightCoop is an unofficial mod — it is careful with guest saves, but a copy costs you nothing.

Requirements

Check	Requirement
Game	A licensed Cyberpunk 2077 on Windows — Steam, GOG or Epic. Each build lists the game patches it supports (currently patch 2.5 and 2.31)
System	Windows 10 or 11, 64-bit
Loader	RED4ext 1.30 — already inside the official archive, no separate install. Cyber Engine Tweaks is not required
Group rule	Every player must run the same NightCoop build and the same game patch, or the session won't connect

Install

1
Back up saves
Copy the save folder to somewhere safe before the first session.
2
Download the agreed build
Get the archive from the official page — pick whichever build your group is playing; all listed builds note their supported game version and SHA-256.
3
Verify the file (optional but smart)
In PowerShell: Get-FileHash .\NightCoop-<version>.zip -Algorithm SHA256 — the string must match the hash published with that build.
4
Extract into the game folder
Unzip the whole archive into the Cyberpunk 2077 directory and replace files — the bin and red4ext folders from the archive merge over the game's.
5
Confirm and launch
Check that Cyberpunk 2077\red4ext\plugins\NightCoop\NightCoop.dll exists, then start the game — a Co-op item should appear in the main menu.
6
Host or join
Host: Co-op → Host a session. Guests: Co-op → Join by code, using the invite the host copies. The host's save drives the shared world; guests bring their own V.

Where is the game folder? Steam: right-click the game → Manage → Browse local files (usually steamapps\common\Cyberpunk 2077). GOG Galaxy and Epic have a similar "show folder" option under Manage.

"Co-op" doesn't show in the menu

Symptom	Likely cause	Fix
No Co-op item at all	Extra nested folder from the archive — the dll landed one level too deep	Check `red4ext\plugins\NightCoop\NightCoop.dll` sits at that exact path
Plugin fails to load	Game patch not in the build's supported list	Read `red4ext\logs` for the reason; switch to a build that lists your patch
Can't join friends	Mismatched mod builds or game versions in the group	Everyone compares build numbers first — "it works for him" proves nothing
Random crashes after install	Files mixed from two different builds	Delete and re-extract one clean build over the game folder

FAQ

Is NightCoop free?

Yes — every released build is free on the official page. You only need a legitimate copy of Cyberpunk 2077.

Is this the cyberpunk co-op mod everyone is talking about?

Yes — NightCoop is the fan project that adds shared-world co-op (up to 8 players) to Cyberpunk 2077. Whether you searched nightcoop, night coop, a cyberpunk co op mod or cyberpunk co-op mod, this is the one.

Do I need to install RED4ext separately?

No — RED4ext 1.30 ships inside the archive. Cyber Engine Tweaks is not required either.

Is NightCoop safe / official?

It is an unofficial fan mod — not made or endorsed by CD Projekt Red. It doesn't touch paid content and the team publishes SHA-256 hashes per build so you can verify downloads.
