一个用于《Subnautica 2》的多人会话人数上限配置覆盖包。
本项目只提供 Unreal Engine 用户配置覆盖文件，用于尝试让游戏在创建多人会话时读取更高的玩家人数参数。它不会修改游戏可执行文件，不会注入 DLL，也不会绕过 EOS、Steam 或官方在线服务校验。
Known issue / 已知问题: Joining as the 5th player may crash or interrupt the game process. This indicates the player limit is likely enforced by game runtime code or online session validation, not only by Game.ini. 第 5 名玩家加入时可能导致游戏进程中断，说明人数上限很可能由游戏运行时代码或在线会话校验强制控制，而不是单纯由 Game.ini 决定。
- 尝试覆盖多人会话人数相关配置
- 默认把人数上限参数设置为
8 - 自动备份已有的
Game.ini - 提供一键安装和卸载脚本
- 不修改游戏本体文件

核心配置位于：
SN2_PlayerLimit_ConfigMod/Config/Game.ini
默认内容：
[/Script/UWESonar.UWEOnlineSessionSubsystem]
MaxSessionPlayerCount=8
MaxPlayerCount=8
NumPublicConnections=8
[/Script/UWESonar.UWEHostSessionRequest]
MaxSessionPlayerCount=8
MaxPlayerCount=8
NumPublicConnections=8
[/Script/UWELobby.UWELobbyGameMode]
MaxSessionPlayerCount=8
MaxPlayerCount=8
NumPublicConnections=8下载或克隆本项目到任意位置，例如游戏目录旁边。
打开：
SN2_PlayerLimit_ConfigMod/Config/Game.ini
把里面的 8 改成你想测试的人数，例如：
MaxSessionPlayerCount=10
MaxPlayerCount=10
NumPublicConnections=10建议先从较小数值测试，例如 6 或 8。
在 PowerShell 中进入项目目录：
cd "你的路径\SN2_PlayerLimit_ConfigMod"运行安装脚本：
.\install.ps1脚本会把配置复制到：
%LOCALAPPDATA%\Subnautica2\Saved\Config\Windows\Game.ini
如果目标位置已经存在 Game.ini，脚本会先创建备份文件，例如：
Game.ini.backup-20260515-153000
启动《Subnautica 2》，创建新的多人会话，然后测试是否可以邀请超过默认人数的玩家。
在 PowerShell 中进入项目目录，然后运行：
.\uninstall.ps1脚本会删除：
%LOCALAPPDATA%\Subnautica2\Saved\Config\Windows\Game.ini
如果你安装前已有自己的 Game.ini，可以在同一目录中找到安装脚本生成的备份文件，并手动恢复。
这很正常。该项目只是配置覆盖尝试，不保证一定生效。
如果游戏忽略这些配置，说明人数上限很可能在以下位置之一被强制控制：
- 打包后的 Unreal Engine 蓝图或数据资产
Subnautica2-Win64-Shipping.exe中的运行时代码- EOS、Steam 或官方在线服务的会话校验
在这些情况下，单纯修改 Game.ini 无法突破限制。
不会。安装脚本只写入用户配置目录：
%LOCALAPPDATA%\Subnautica2\Saved\Config\Windows\Game.ini
不会修改游戏目录里的 .exe、.dll、.pak、.ucas 或 .utoc 文件。
可以编辑 Config/Game.ini 后自行测试，但不建议一开始设置过高。即使配置被读取，游戏逻辑、网络同步、性能、存档和在线服务也可能无法承受更高人数。
当前配置基于 Windows 版《Subnautica 2》的常见 Unreal Engine 配置路径：
%LOCALAPPDATA%\Subnautica2\Saved\Config\Windows
不同版本、平台或更新后的游戏构建可能不再读取这些配置项。
本项目仅用于配置覆盖测试和学习研究。
使用前请自行备份存档和配置文件。作者不保证该配置一定生效，也不对游戏崩溃、联机异常、存档损坏、账号风险或违反游戏/平台服务条款造成的后果负责。

A player-limit configuration override package for multiplayer sessions in Subnautica 2.
This project only provides Unreal Engine user configuration overrides. It attempts to make the game read higher player-count values when creating a multiplayer session. It does not modify the game executable, inject DLLs, or bypass EOS, Steam, or official online-service validation.
- Attempts to override multiplayer session player-count settings
- Sets the default player-count values to
8 - Automatically backs up an existing
Game.ini - Provides simple install and uninstall scripts
- Does not modify the original game files

Main configuration file:
SN2_PlayerLimit_ConfigMod/Config/Game.ini
Default contents:
[/Script/UWESonar.UWEOnlineSessionSubsystem]
MaxSessionPlayerCount=8
MaxPlayerCount=8
NumPublicConnections=8
[/Script/UWESonar.UWEHostSessionRequest]
MaxSessionPlayerCount=8
MaxPlayerCount=8

[/Script/UWELobby.UWELobbyGameMode]
MaxSessionPlayerCount=8
MaxPlayerCount=8
NumPublicConnections=8Download or clone this project to any location, such as next to your game folder.
Open:
SN2_PlayerLimit_ConfigMod/Config/Game.ini
Change every 8 to the value you want to test, for example:
MaxSessionPlayerCount=10
MaxPlayerCount=10
NumPublicConnections=10It is recommended to start with a smaller value such as 6 or 8.
Open PowerShell and enter the project folder:
cd "YourPath\SN2_PlayerLimit_ConfigMod"Run the install script:
.\install.ps1The script copies the config to:
%LOCALAPPDATA%\Subnautica2\Saved\Config\Windows\Game.ini
If a Game.ini already exists there, the script creates a backup first, for example:
Game.ini.backup-20260515-153000
Launch Subnautica 2, create a new multiplayer session, and test whether the game allows more players than the default limit.
Open PowerShell in the project folder and run:
.\uninstall.ps1The script removes:
%LOCALAPPDATA%\Subnautica2\Saved\Config\Windows\Game.ini
If you had your own Game.ini before installing, restore the backup created by the installer from the same folder.
That can happen. This project is only a configuration override attempt and is not guaranteed to work.
If the game ignores these settings, the player limit is likely enforced by one of the following:
- Packaged Unreal Engine blueprints or data assets
- Runtime code inside
Subnautica2-Win64-Shipping.exe - EOS, Steam, or official online-service session validation
In those cases, changing Game.ini alone cannot bypass the limit.
No. The install script only writes to the user configuration path:
%LOCALAPPDATA%\Subnautica2\Saved\Config\Windows\Game.ini
It does not modify .exe, .dll, .pak, .ucas, or .utoc files in the game directory.
You can edit Config/Game.ini and test higher values, but very high values are not recommended. Even if the config is read, gameplay logic, network synchronization, performance, saves, and online services may not support higher player counts.
This configuration is based on the common Unreal Engine user config path used by the Windows version of Subnautica 2:
%LOCALAPPDATA%\Subnautica2\Saved\Config\Windows
Different versions, platforms, or future game updates may stop reading these settings.
This project is provided only for configuration override testing and educational research.
