StayInTarkov.Client

An Escape From Tarkov BepInEx module designed to be used with the SIT.Aki-Server-Mod with the ultimate goal of "Offline" Coop

About

The Stay in Tarkov project was born due to Battlestate Games' (BSG) reluctance to create the pure PvE version of Escape from Tarkov. The project's aim is simple, create a Cooperation PvE experience that retains progression. If BSG decide to create the ability to do this on live OR we receive a DCMA request, this project will be shut down immediately.

Warning

Due to the popularity of the project. There are numerous forks and scam projects appearing online of Stay in Tarkov. Please be aware of these scams. SIT will always be free and open source. Any projects that are closed source and requiring payment are a scam.

Disclaimer

You must buy the game to use this. You can obtain it here. https://www.escapefromtarkov.com.
This is by no means designed for cheats (this project was made because cheats have destroyed the Live experience)
This is by no means designed for illegally downloading the game (and has blocks for people that do!)
This is purely for educational purposes. We can learn a lot from BattleState Games \o/
I (Paulov) am not affiliated with BSG or others (on Reddit or Discord) claiming to be working on a project. Do NOT contact SPTarkov subreddit or Discord about this project
This project is not affiliated with SPTarkov (SPT-Aki) but uses its excellent Server
This project is not affiliated with any other Escape from Tarkov emulator
This project does not want forks to release closed source and paygated emulators

SPT-AKI Requirement

Stay in Tarkov requires the latest AKI Server to facilitate coop connections. You can learn about SPT-Aki here.
NOTE: The SIT Client Mod should NOT be installed onto the SPT-Aki Client- it should be installed onto it's own copy of Tarkov. See the Installation>Client section of this readme for further info.

Wiki

The Wiki is has been constructed by various contributors. All instructions are also kept within the source in the wiki directory.

Installation

Overview

SIT is comprised of 2 major pieces and a launcher

The SIT SPT-Aki Server Mod
The SIT Client Module (this repo!), installed onto an instance of Tarkov
SIT Manager or SIT Launcher Classic
- You should use the SIT Manager. The classic launcher is only mentioned to clarify for existing classic launcher users.

It's recommended to create the following directory structure to store your SIT Installation. This structure will be referred to for the following sections.

SIT/
├── server/      # SPT-Aki Server Mod
├── game/        # EFT Client
└── launcher/    # SIT Manager or Classic Launcher

Server Install

Follow the instructions in the SIT SPT-Aki Server Mod repo to install and configure the server into the SIT/server folder.
Exactly one person needs to run the server for Coop. This person will need to port forward, or your group will have to connect via Hamachi or some other VPN solution. If you don't know how to do these things, you might see if someone in the SIT discord is willing to help.
- In vanilla SPT, you're probably used to running your own local server, and then launching your client which connects to that server under the hood. With SIT, one person will run the modded server and everyone else will connect to that server over the internet.

Launcher Install

Follow the instructions in the SIT Manager repo. Install into the SIT/launcher folder.

Client Install

Everyone must install the SIT Client Mod. You can install it using SIT Manager, or manually if desired.
IF YOU USE SPT ALREADY: Do NOT install the SIT Client mod onto your existing SPT install. The SIT Client Mod is currently not compatible with the SPT-Aki client, so it needs to be installed on it's own copy of Tarkov.
NOTE: As of 05/02/2024 the downgraders used by the manager and in the link provided for the manual install will not downgrade to the correct version and/or fail. Please check the SIT Discord for the latest EFT downgrader

SIT Manager Method

Copy the contents of your live EFT installation into the currently-empty SIT/game folder
- If you installed tarkov to the default location, it will be under C:\Battlestate Games\EFT.
Launch SIT/launcher/SIT.Manager.exe
Point the manager to the target game directory
- Open Settings in the bottom left
- Set Install Path to X:\<Full_Path_To>\SIT\game, or use the Change button and select the SIT/game folder
  - Replace X and <Full_Path_To> with the path to the folder.
- Close Settings
Open the Tools menu on the left, and select + Install SIT
Select the desired SIT version (choose the latest if you don't know what you're doing)
Click Install

Manual install method

Note that these are the same steps the SIT Manager performs. If you don't have any reason to, you should probably just use the SIT manager- it's so much quicker and easier. (Seriously, we're not hiding anything from you here. These steps are literally just a plain-english description of [the manager code](https://github.com/stayintarkov/SIT.Manager/blob/master/SIT.Manager/Classes/Utils.cs#L613))

Copy the contents of your live EFT installation into the currently-empty SIT/game folder
- If you installed tarkov to the default location, it will be under C:\Battlestate Games\EFT.
Create the folowing directories in SIT/game:
- SITLauncher/
- SITLauncher/CoreFiles/
- SITLauncher/Backup/Corefiles/
Download the desired version of the client-mod from this repo's releases page to SIT/game/SITLauncher/CoreFiles (choose the latest if you don't know what you're doing)
- Create the folder SIT/game/SITLauncher/CoreFiles/StayInTarkov-Release/
- Extract the contents of the release archive into that folder
Clean up your SIT/game directory
- Delete the following files & directories:
  - BattleEye/ *
  - EscapeFromTarkov_BE.exe *
  - cache/
  - ConsistencyInfo
  - Uninstall.exe
  - Logs/
- * In case of concern, note that this is not a method that can be used to cheat in live tarkov. SPT (and SIT, by extension) don't use the BattleEye executables/files because the SPT-Aki server does not run battleeye. Please be careful, and don't delete these files from your live directory. At best you'll brick your install & won't be able to connect to live servers. At worst you'll trigger a BattleEye detection and get your Account/IP/HWID marked for doing.
Downgrade your copied tarkov if necessary
- If your live tarkov's version isn't the same as the SIT version you chose in step 3, you need to downgrade.
  - Your live tarkov's version is the 5-part number in the bottom right of the BSG launcher.
- SIT does not maintain the tools to downgrade tarkov. You can find instructions on downgrading tarkov here
  - Follow steps 7, 8, 9. Use any folder for the "DowngradePatchers" folder, and use the SIT/game folder for the "SPTARKOV" folder.
  - If you run into issues here, SIT does not maintain the DowngradePatcher. You can contact the SPT devs about it, but understand that they won't provide support for anything else than the patcher- Do NOT ask them for help with other SIT topics, they will not help you.
    - That said, if whatever issue you have is legitimate and not just a simple error, the SIT team has probably already noticed & reported it. The SIT Manager uses the Downgrade Patcher too.
Install BepInEx v5.4.22
- Download the archive
- Extract the contents to SIT/game
  - Your SIT/game folder should now contain a BepInEx folder, a doorstop_config.ini file, a changelog.txt file, and a winhttp.dll file.
- Make the SIT/game/BepInEx/plugins folder
Install SIT Client DLLs
- Assembly-CSharp.dll
  - Make a backup of your original SIT/game/EscapeFromTarkov_Data/Managed/Assembly-CSharp.dll to SIT/game/SITLauncher/Backup/CoreFiles/
  - Replace the original dll with SIT/game/SITLauncher/CoreFiles/StayInTarkov-Release/Assembly-CSharp.dll
- Copy SIT/game/SITLauncher/CoreFiles/StayInTarkov-Release/StayInTarkov.dll to SIT/game/BepInEx/plugins/
Install Aki Client DLLs
- Download the latest SPT-AKI release from the SPT releases page
- Extract two files EscapeFromTarkov_Data/Managed/Aki.Common.dll and EscapeFromTarkov_Data/Managed/Aki.Reflection.dll from the release, into SIT/game/EscapeFromTarkov_Data/Managed/ And with any luck, you're done.

Playing

Server Host Only: Have the server-host start up the modded server (port forwarded / tunneled via VPN or Hamachi to the rest of your group)
- Make sure you configured your IP address(es) per the servermod repo instructions!
Everyone: Start up the SIT Manager, enter the host's IP & port, and click play!
- Anyone can start a raid lobby, just select the location/time/insurance, click Host Raid, configure the exact number of players & desired settings, and start it up. Everyone else will see the lobby pop up after you start, and will join then. (The game won't start till everyone's loaded, just like regular tarkov)

FAQ

Can Coop use BSG's Coop code?

No. BSG server code is hidden from the client for obvious reasons. So BSG's implementation of Coop use the same online servers as PvPvE. We don't see this, so we cannot use this.

Are Aki BepInEx (Client mods) Modules supported?

The following Aki Modules are supported.

aki-core
Aki.Common
Aki.Reflection

Do SPT-AKI Client mods work?

This is dependant on how well written the patches are. If they directly target GCLASSXXX or PUBLIC/PRIVATE then they will likely fail.

Why don't you use Aki Module DLLs?

SPT-Aki DLLs are written specifically for SPT-Aki own Deobfuscation technique and Paulov's own technique does not work with Aki Modules.
