How to Install Ready or Not Mods in 2026

Ready or Not mods install in three current ways on PC: the official in-game Mod.io menu, Nexus Mods through Vortex, and manual .pak files. The fastest path is Mod.io because VOID points official mod support there. Use Vortex or manual files only when the mod page provides that install method.

1. Install Mods From the Official Mod.io Menu

1. 1.Install Ready or Not on a Windows PC from Steam, the Epic Games Store, or the Microsoft Store / Xbox Play Anywhere PC build. Mods load on all three PC builds; the Steam local-file paths later in this guide are Steam-only.
2. 2.Launch Ready or Not.
3. 3.From the main menu, open Mods / Mod.io.
4. 4.Log in or authenticate your mod.io account when prompted.
5. 5.Use Browse or Search to find the mod.
6. 6.Select Subscribe or the install option shown in the in-game menu.
7. 7.Select Restart when prompted, or let Ready or Not download and apply the subscribed mod.

2. Subscribe on Mod.io Before Launching the Game

1. 1.Open the Ready or Not page on mod.io.
2. 2.Choose a mod and select Subscribe.
3. 3.For a group of mods, open Collections, choose a collection, and select Subscribe.
4. 4.Launch Ready or Not.
5. 5.Open Main Menu > Mods / Mod.io.
6. 6.Sign in with the same mod.io account and wait for the subscribed content to download.

Use the same mod.io account in your browser and in Ready or Not so your subscriptions appear in-game.

3. Use Vortex for Nexus Mods Downloads

This fixes the handoff from a Nexus mod page to your Ready or Not install when that mod supports Vortex.

1. 1.Open Nexus Mods and go to Vortex.
2. 2.Select Download for Windows, or open the Nexus Mods Vortex files page and select the Vortex installer download.
3. 3.Run the installer and follow the prompts.
4. 4.Sign in to Nexus Mods inside Vortex.
5. 5.In Vortex, manage Ready or Not after it is detected and supported.
6. 6.On a Ready or Not mod page, choose Mod Manager Download or Vortex when offered.
7. 7.In Vortex, select Install, then select Enable or Deploy.

4. Place a Manual Pak Mod in the Paks Folder

Manual install is the fallback for Ready or Not mods that ship as .pak files instead of Mod.io subscriptions or Vortex downloads. In Steam, open Steam > Library > Ready or Not > Manage > Browse local files, then go to ReadyOrNot > Content > Paks and copy the downloaded mod's .pak file into that folder. Launch Ready or Not after the copy finishes. Current Nexus Ready or Not mod pages still use this path, and each mod must match the current game build.

5. Repair a Blank Mod.io Menu

This fixes a blank Ready or Not Mod.io menu or a mod.io account link that needs fresh authentication.

1. 1.Right-click Start and choose Run.
2. 2.Type %localappdata% and open it.
3. 3.Open the mod.io folder.
4. 4.Open the folder with the 4-digit game ID.
5. 5.Open the next folder until you find user.json.
6. 6.Rename user.json to user.json.BAK.
7. 7.Restart Ready or Not.
8. 8.Open the mod menu and reauthenticate with mod.io.

6. Remove or Disable Mods Cleanly

1. 1.For Mod.io mods, launch Ready or Not and open Main Menu > Mods / Mod.io.
2. 2.Open your subscribed or installed mod list and select Unsubscribe on the mod you want to remove.
3. 3.For a broader Mod.io reset, open Options > Gameplay > Clear Mod.io User Data.
4. 4.To launch once without mods, open Steam > Library, select Play on Ready or Not, then choose Safe Mode.
5. 5.For manual .pak mods, open Steam > Library > Ready or Not > Manage > Browse local files > ReadyOrNot > Content > Paks, delete the mod-added .pak or .utxt files, and leave the base game files in place.
6. 6.Restart Ready or Not.

Safe Mode is temporary; unsubscribing, clearing Mod.io data, or deleting the added files is the cleanup step.

7. Let Modded Multiplayer Connect

1. 1.Launch Ready or Not.
2. 2.Open Main Menu > Settings > Gameplay Options, listed as Options > Gameplay in older builds.
3. 3.Set Server-Side Checksum to Off if your build still lists it.
4. 4.To host, turn on Allow Modded Players, or just host while modded; either one makes it a modded lobby.
5. 5.To join while modded, expect modded lobbies only. To join a modded lobby while unmodded, turn on Join Modded Lobbies.
6. 6.Host or join the intended modded lobby.
7. 7.Confirm every player has the required gameplay or content mods for that lobby.

8. Skip Old Steam Workshop and Loader Advice

Older Ready or Not mod guides point to Steam Workshop or legacy loader steps. For the current Steam version, the product page does not list Steam Workshop support, and VOID points official mod support to Ready or Not > Main Menu > Mods / Mod.io. Some older loader pages also mention functionality that was folded into the base game after the LSS Patch 2 update, so use current Mod.io, Vortex, or updated .pak instructions instead.

Frequently Asked Questions

Does Ready or Not support Steam Workshop mods?

The current Steam product page does not list Steam Workshop support for Ready or Not. Use the in-game Mod.io menu for the official mod path.

Can I install Ready or Not mods on PS5 or Xbox Series X/S?

No current console mod browser, file-install workflow, or account portal was verified in the provided research. Use the unmodded console game unless VOID adds console mod support later.

Why do I get a checksum mismatch in a modded lobby?

Open Ready or Not and go to Main Menu > Settings > Gameplay Options, listed as Options > Gameplay in older builds, then turn Server-Side Checksum off if your build still lists it. Since LSS Patch 2, modded matchmaking also depends on the lobby rules: hosting with Allow Modded Players on, or hosting while modded, makes it a modded lobby; modded players can only join modded lobbies; and unmodded players need Join Modded Lobbies enabled to get into one. Players still need the required gameplay or content mods for that lobby.

How do I remove a manual .pak mod?

Open ReadyOrNot > Content > Paks from the Steam Browse local files path, delete only the mod-added .pak or .utxt files, and restart the game. Leave the base game files in place.
