1. MDL3 是什么
MDL3 是一个在游戏内运行的 MOD 加载与管理器。它在 ESC 菜单里加一个 MDL Settings 页签，你可以在里面查看、启动、停止、重载 MOD，不需要退出游戏。MDL3 是 MDL 2.x 的后继版本，界面和大部分功能沿用 MDL 2。
2. 它和其他 MOD 加载器有什么不同
2.1 MDL3 不取代你的 MOD 管理器
- Arsenal、Echelon、HD2MM 这类工具负责安装和部署：把 MOD 放进游戏，改完要重启游戏才生效。
- MDL3 在游戏运行期间管理 MOD 的启动和停止。
2.2 两个主要区别
① 带有 FFIMDL3 带有 FFI，可以读取游戏本身不对 MOD 开放的数据。这让很多以前做不出来的 MOD 成为可能。在预览版中，这些数据通过附带的 HD2 Data Hub 提供给 MOD（见第 4 节）。
② 随时开关 MOD，方便调试
| 改了 MOD 后想看效果 | 重新部署 → 重启游戏 | 在游戏里直接重载 |
| 怀疑某个 MOD 导致问题 | 逐个停用 → 部署 → 重启，反复多次 | 在游戏里逐个关掉，马上看到效果 |
| 某个 MOD 只想这局用 | 部署 → 重启 | 在库里直接启动，不需要部署 |
| 某个 MOD 一启动游戏就卡死 | 很难排查 | 安全模式：只启动 MDL3，再手动逐个启动 |
此外，MDL3 还能：
- 显示每个 MOD 的运行状态和出错信息；
- 自动停止反复出错的 MOD；
- 在专业模式中显示每个 MOD 占用的帧耗时，帮你找出拖慢游戏的 MOD；
- 集中显示各个 MOD 的选项和按键设置。
2.3 兼容性
- 依赖 BSL（Bingus Shared Loader）的 MOD 一般可以照常使用。
- 不要同时部署其它同类加载器（例如 BSL 本体或 MDL 2.x），否则会冲突。
3. 预览版说明
这是预览版，不是正式版。3.1 预览版是纯读取的
预览版只读取游戏数据，不做任何写入或修改。 MOD 通过附带的 HD2 Data Hub 获取这些数据。3.2 已可用的功能
- ESC 菜单的 MDL Settings 页签；
- MOD 库：显示 Arsenal / Echelon / HD2MM 中的 MOD，按类型分组，并合并重复的条目；
- 脚本 MOD 的游戏内启动 / 停止 / 重载；
- 已部署的脚本 MOD 也可以在游戏内开关；
- 记住你启用了哪些 MOD；
- 安全模式；
- MOD 的选项和按键设置页；
- 界面多语言（自动跟随游戏 / Steam / Windows 语言）。
3.3 暂不支持或有限制
- 资源 MOD（模型、贴图、音频替换等）不能在游戏内开关。 它们在库里显示为 LAUNCH ONLY，仍需在 Arsenal 中启用或停用，部署后重启游戏。
- 混合 MOD（同时包含脚本和资源）在游戏内只能开关脚本部分。
- 少数 MOD 无法被完全关掉，MDL3 会标注“关（未完全，重启后清除）”。遇到这种情况请重启游戏。
- 游戏更新后，Data Hub 可能需要等作者适配。适配前它会显示 unsupported，并暂停读取。
3.4 预览版的风险
预览版没有经过长时间、大规模的测试，可能出现崩溃、卡顿、MOD 行为异常、设置丢失等问题。请不要在你无法承受损失的情况下使用。4. 附带的 HD2 Data Hub
HD2 Data Hub 是随 MDL3 附带的一个 MOD，为其他 MOD 提供它们需要的游戏数据，例如：- 本地玩家的生命值、状态、位置、武器、配装和弹药；
- 小队成员；
- 任务开始 / 结束；
- 敌人生成、受伤、死亡，玩家开火、命中、击杀，爆炸，战略配备的呼叫与使用等事件。
作为 MOD 作者： Data Hub 包内附有接口说明，你的 MOD 只需读取它提供的数据。请在你的 MOD 说明里写明这个依赖，并链接到 MDL3 官方发布页（见第 9 节），不要把 Data Hub 打包进你自己的 MOD。
5. 安装
5.1 你需要
- Helldivers 2（PC / Steam）
- 一个 MOD 管理器：Arsenal（推荐）、Echelon 或 HD2MM
- 从官方发布页下载的 MDL3 预览版压缩包
5.2a 步骤(自动安装)
- 解压下载的压缩包。
- 在 Arsenal 中导入 MDL3 的 MOD 包，启用并 Deploy。
- 如果你要使用依赖它的 MOD，在 Arsenal 中导入、启用并部署 HD2 Data Hub。
- 从 Steam 正常启动游戏，按 ESC，首次安装你会看见诊断模式，跟随指示进行安装和配置
- 完成后重新启动，享受游戏。
5.2b 步骤(手动安装)
- 解压下载的压缩包。
- 运行安装脚本：直接戳那个INSTALL.bat！！！
- 在 Arsenal 中导入 MDL3 的 MOD 包，启用并 Deploy。
- 如果你要使用依赖它的 MOD，在 Arsenal 中导入、启用并部署 HD2 Data Hub。
- 从 Steam 正常启动游戏，按 ESC，确认出现 MDL Settings 页签。
5.3 卸载
- 退出游戏。
- 在 Arsenal 中停用 MDL3 和 HD2 Data Hub，并重新 Deploy。
- 在解压的文件夹中运行：
Code:powershell -NoProfile -ExecutionPolicy Bypass -File .\install.ps1 -Action Remove
6. 配合 Arsenal（或其它 MOD 管理器）使用
6.1 分工
| 导入 MOD | Arsenal / Echelon / HD2MM |
| 部署资源 MOD（模型、贴图等），需重启游戏 | Arsenal / Echelon / HD2MM |
| 部署 MDL3 本身和 HD2 Data Hub | Arsenal / Echelon / HD2MM |
| 游戏内启动 / 停止 / 重载脚本 MOD | MDL3 |
| 查看 MOD 的运行状态和出错信息 | MDL3 |
6.2 推荐流程
- 在 Arsenal 中导入所有你想用的 MOD。
- 资源 MOD，以及你希望每次都随游戏启动的 MOD：在 Arsenal 中启用并部署。
- 脚本 MOD：可以只导入、不部署，进游戏后在 MDL3 的 MOD 库里直接启动。MDL3 会记住你启用了哪些。
- 在 Arsenal 中更新某个 MOD 后，MDL3 会自动发现变化，正在运行的可以直接重载。
6.3 已部署的脚本 MOD
在 Arsenal 中已部署的脚本 MOD，同样可以在 MDL3 里开关：- 关掉后立即停止，下次启动游戏时也会跳过它，不需要回 Arsenal 取消部署；
- 再打开后立即恢复。
6.4 Echelon 与 HD2MM
MDL3 同样显示 Echelon 和 HD2MM 中的 MOD。同一个 MOD 在多个管理器里都有时会合并为一行，名字下方的小标签显示来源。建议只用一个管理器部署 MOD，避免重复部署。6.5 注意
- 不要把 MDL3 部署两次（例如 Arsenal 和 HD2MM 各部署一份）。
- 升级 MDL3 时，请在 Arsenal 中替换旧版本，而不是再添加一个；如果更新说明要求，再运行一次安装脚本。
7. 游戏内使用与问题排查
7.1 使用
- 按 ESC → MDL Settings。
- MOD 库分组显示：SCRIPT - LIVE 可以在游戏内开关；LAUNCH ONLY 只能通过 Arsenal 部署。点 LAUNCH ONLY 旁的 “?” 可以查看原因和 Arsenal 操作步骤。
- 点进一个 MOD：启动、停止、重载，查看说明和出错信息，修改它的选项和按键。
- 专业模式（设置列表最后一行）：显示每个 MOD 的帧耗时等数据。
7.2 安全模式
如果某个 MOD 导致游戏一启动就卡死或崩溃，可以开启安全模式：游戏只启动 MDL3，其它 MOD 暂不启动，你可以在面板中逐个手动启动来找出问题 MOD。- 开启：在 Arsenal 中启用并部署压缩包附带的安全模式包。
- 退出：停用安全模式包并重新部署。
7.3 常见问题排查
- ESC 里没有 MDL Settings：确认已运行安装脚本，MDL3 已在 Arsenal 中启用并部署，没有同时部署其它同类加载器。
- 某个 MOD 显示 LAUNCH ONLY：它包含资源，需要在 Arsenal 中部署并重启游戏。
- Data Hub 显示 unsupported：当前游戏版本还没有适配，请等待更新。
- 游戏更新后出问题：先开启安全模式确认是否是 MOD 引起，再等待 MDL3、Data Hub 或相关 MOD 的更新。
7.4 反馈问题
请附上以下日志、MDL3 版本号和你启用的 MOD 列表：%LOCALAPPDATA%\MDL\Helldivers2\Logs\文件夹中的日志%LOCALAPPDATA%\MDL3\Logs\文件夹中的日志

- 请勿以任何方式让用户跳过本页面获得 MDL3。
10. 为什么 MDL3 不开源
很多人会问：既然是免费工具，为什么不开源？以下是我的真实理由。我非常担心它被滥用，被随意改造后再分发。
MDL3 带有 FFI，这类技术本身非常强大。一旦被别人拿去改造，就可能被做成：
- 作弊工具，破坏其他玩家的体验；
- 盗号、窃取数据之类的恶意程序，伪装成“某某 MOD 需要的 MDL3”；
- 不稳定的改版，导致大量崩溃，而用户以为是 MDL3 本身的问题。
如果开源，任何人都可以：
- 在源码基础上自行加入写入之类的功能，再以 MDL3 的名义分发；
- 换个名字或者干脆用同样的名字分发，用户很难分辨哪个是原版、哪个被动过手脚；
- 出现大量互不兼容的分支，MOD 作者和用户都要承担混乱的代价。
我也清楚，闭源并不能保证绝对安全。但它至少提高了制作恶意改版的门槛，也让“只有官方发布页的文件是可信的”这条规则可以执行。
这也是第 9 节要求不得未经授权分发、必须附带本页面的原因：我希望每一个使用 MDL3 的人，都是从可信的来源拿到它，并且清楚它能做什么、有什么风险。
如果你有正当的理由需要更深入地了解它（例如安全审查或合作开发），可以联系我单独沟通。
11. 常见问题
Q：装了 MDL3 还需要 Arsenal 吗？ A：需要。MDL3 自己要通过 Arsenal 等管理器部署，资源 MOD 也仍要通过管理器部署。MDL3 负责的是游戏内的管理和开关。Q：预览版能做修改游戏数据的 MOD 吗？ A：不能。预览版是纯读取的。
Q：我以前用的 MOD 依赖 BSL，在 MDL3 下还能用吗？ A：一般可以。但不要同时部署 BSL 本体。
Q：游戏更新后还能用吗？ A：MOD 管理功能通常不受影响；Data Hub 需要等作者适配，适配前会显示 unsupported 并暂停读取。
Q：我可以把 MDL3 放进我的整合包吗？ A：未经书面授权不可以。请在整合包说明中链接到官方发布页。
Q：会被封号吗？ A：作者无法保证。请阅读第 8 节，并自行判断是否使用。
本页是 MDL3 的一部分，必须随 MDL3 一起完整、未经修改地提供。最终版本以官方发布页为准。

1. What is MDL3?
MDL3 is a mod loader and manager that runs inside the game. It adds an MDL Settings tab to the ESC menu, where you can view, start, stop and reload mods without leaving the game.MDL3 is the successor to MDL 2.x. Its interface and most of its features carry over from MDL 2.
2. How is it different from other mod loaders?
2.1 MDL3 does not replace your mod manager
- Tools such as Arsenal, Echelon and HD2MM install and deploy mods. They put mods into the game, and changes take effect only after you restart the game.
- MDL3 manages mods while the game is running, starting and stopping them as you choose.
2.2 Two key differences
① FFI supportMDL3 includes FFI, so it can read game data that the game normally does not expose to mods. This makes many previously impossible mods possible. In the preview, this data is provided to mods through the bundled HD2 Data Hub (see Section 4).
② Turn mods on and off at any time — easier debugging
| You changed a mod and want to see the result | Redeploy → restart the game | Reload it in game |
| You suspect a mod is causing a problem | Disable one by one → deploy → restart, again and again | Turn mods off one by one in game and see the effect immediately |
| You want a mod for this session only | Deploy → restart | Start it straight from the library, no deploy needed |
| A mod freezes the game at launch | Hard to track down | Safe mode: start only MDL3, then start mods one by one |
MDL3 also:
- shows each mod's status and errors;
- automatically stops mods that keep failing;
- shows each mod's per-frame cost in Pro mode, helping you find mods that slow the game down;
- brings every mod's options and key bindings together in one place.
2.3 Compatibility
- Mods that depend on BSL (Bingus Shared Loader) generally work as usual.
- Do not deploy other loaders of the same kind at the same time (such as BSL itself or MDL 2.x). They will conflict.
3. About the preview
This is a preview, not a final release.3.1 The preview is read-only
The preview only reads game data. It does not write or modify anything. Mods get this data through the bundled HD2 Data Hub.3.2 Available features
- The MDL Settings tab in the ESC menu;
- Mod library: shows mods from Arsenal / Echelon / HD2MM, grouped by type, with duplicate entries merged;
- Starting / stopping / reloading script mods in game;
- Turning already-deployed script mods on and off in game;
- Remembering which mods you enabled;
- Safe mode;
- Options and key-binding pages for mods;
- Multi-language interface (automatically follows the game / Steam / Windows language).
3.3 Not yet supported / limitations
- Resource mods (models, textures, audio replacements, etc.) cannot be toggled in game. They appear as LAUNCH ONLY in the library and must still be enabled or disabled in Arsenal, deployed, and the game restarted.
- Mixed mods (containing both scripts and resources) can only have their script part toggled in game.
- A few mods cannot be fully turned off. MDL3 marks them as "Off (incomplete, cleared on restart)". If this happens, restart the game.
- After a game update, Data Hub may need to wait for the author to update it. Until then it shows unsupported and stops reading.
3.4 Preview risks
The preview has not gone through long-term or large-scale testing. It may cause crashes, stutter, unexpected mod behaviour, lost settings or other problems. Do not use it if you cannot accept such losses.4. The bundled HD2 Data Hub
HD2 Data Hub is a mod bundled with MDL3 that provides other mods with the game data they need, for example:- the local player's health, status, position, weapons, loadout and ammo;
- squad members;
- mission start / end;
- events such as enemy spawns, damage and deaths, player shots, hits and kills, explosions, and stratagem calls and uses.
For mod authors: the Data Hub package includes its interface documentation; your mod simply reads the data it provides. State this dependency in your mod's description and link to the official MDL3 release page (see Section 9). Do not bundle Data Hub inside your own mod.
5. Installation
5.1 You need
- Helldivers 2 (PC / Steam)
- A mod manager: Arsenal (recommended), Echelon or HD2MM
- The MDL3 preview archive downloaded from the official release page
5.2a Steps(Auto)
- Extract the downloaded archive.
- Import the MDL3 mod package into Arsenal, enable it and Deploy.
- If you want to use mods that depend on it, import, enable and deploy HD2 Data Hub in Arsenal.
- Start the game normally from Steam, press ESC, and you may see diag mod, follow it and it will fix all these s**t.
- Once you done all stage, re-start to make sure it works.
5.2b Steps(Manual)
- Extract the downloaded archive.
- Run the install script: run INSTALL.bat
- Import the MDL3 mod package into Arsenal, enable it and Deploy.
- If you want to use mods that depend on it, import, enable and deploy HD2 Data Hub in Arsenal.
- Start the game normally from Steam, press ESC, and check that the MDL Settings tab appears.
5.3 Uninstalling
- Exit the game.
- Disable MDL3 and HD2 Data Hub in Arsenal and Deploy again.
- In the extracted folder, run:
Code:powershell -NoProfile -ExecutionPolicy Bypass -File .\install.ps1 -Action Remove
6. Using MDL3 with Arsenal (or another mod manager)
6.1 Who does what
| Importing mods | Arsenal / Echelon / HD2MM |
| Deploying resource mods (models, textures, etc.), restart required | Arsenal / Echelon / HD2MM |
| Deploying MDL3 itself and HD2 Data Hub | Arsenal / Echelon / HD2MM |
| Starting / stopping / reloading script mods in game | MDL3 |
| Viewing mod status and errors | MDL3 |
6.2 Recommended workflow
- Import all the mods you want into Arsenal.
- Resource mods, and mods you want to start with the game every time: enable and deploy them in Arsenal.
- Script mods: you can import them without deploying, then start them straight from the MDL3 library in game. MDL3 remembers which ones you enabled.
- After you update a mod in Arsenal, MDL3 detects the change automatically; if the mod is running, you can simply reload it.
6.3 Deployed script mods
Script mods already deployed in Arsenal can also be turned on and off in MDL3:- Turning one off stops it immediately, and it is skipped the next time the game starts — no need to go back to Arsenal and undeploy it;
- Turning it back on restores it immediately.
6.4 Echelon and HD2MM
MDL3 also shows mods from Echelon and HD2MM. When the same mod exists in several managers, it is merged into one row, with small tags under the name showing where it comes from. We recommend deploying mods with only one manager to avoid duplicate deployments.6.5 Notes
- Do not deploy MDL3 twice (for example, once from Arsenal and once from HD2MM).
- When upgrading MDL3, replace the old version in Arsenal instead of adding another one. If the update notes say so, run the install script again.
7. In-game use and troubleshooting
7.1 Using MDL3
- Press ESC → MDL Settings.
- The mod library is grouped: SCRIPT - LIVE mods can be toggled in game; LAUNCH ONLY mods can only be deployed through Arsenal. Click the "?" next to LAUNCH ONLY to see why and the steps to follow in Arsenal.
- Open a mod to start, stop or reload it, read its description and errors, and change its options and key bindings.
- Pro mode (last row of the settings list): shows per-frame cost and other data for each mod.
7.2 Safe mode
If a mod freezes or crashes the game at launch, turn on safe mode: the game starts only MDL3 and no other mods, so you can start them one by one from the panel to find the problem mod.- To turn on: enable and deploy the safe mode package included in the archive in Arsenal.
- To turn off: disable the safe mode package and deploy again.
7.3 Troubleshooting
- No MDL Settings tab in ESC: check that you ran the install script, that MDL3 is enabled and deployed in Arsenal, and that no other loader of the same kind is deployed.
- A mod shows LAUNCH ONLY: it contains resources; deploy it in Arsenal and restart the game.
- Data Hub shows unsupported: the current game version is not supported yet; please wait for an update.
- Problems after a game update: first use safe mode to check whether a mod is the cause, then wait for updates to MDL3, Data Hub or the mods involved.
7.4 Reporting problems
Please include the following logs, your MDL3 version and the list of mods you have enabled:- the logs in the
%LOCALAPPDATA%\MDL\Helldivers2\Logs\folder - the logs in the
%LOCALAPPDATA%\MDL3\Logs\folder

- Do not offer MDL3 in any way that lets users skip this page.
10. Why MDL3 is not open source
Many people ask: if it's a free tool, why not open source it? Here are my honest reasons.I am genuinely afraid of it being abused, modified and redistributed freely.
MDL3 includes FFI, which is a very powerful technology. In the wrong hands, a modified version could be turned into:
- cheating tools that ruin other players' experience;
- malware that steals accounts or data, disguised as "the MDL3 that some mod needs";
- unstable forks that cause widespread crashes, which users then blame on MDL3 itself.
If it were open source, anyone could:
- add write capabilities or similar features to the source code and distribute the result under the MDL3 name;
- distribute it under a different name, or even the same name, so that users could hardly tell the original from a tampered version;
- create many incompatible forks, leaving mod authors and users to deal with the confusion.
I know that closed source is not a guarantee of absolute safety. But it at least raises the bar for making malicious modified versions, and it makes the rule "only files from the official release page can be trusted" enforceable.
This is also why Section 9 forbids unauthorized redistribution and requires this page to be included: I want everyone who uses MDL3 to get it from a trusted source and to understand what it does and what the risks are.
If you have a legitimate reason to learn more about how it works (for example, a security review or a collaboration), you are welcome to contact me directly.
11. FAQ
Q: Do I still need Arsenal if I have MDL3? A: Yes. MDL3 itself is deployed through Arsenal or another mod manager, and resource mods still need to be deployed through a manager. MDL3 handles in-game management and toggling.Q: Can the preview be used for mods that modify game data? A: No. The preview is read-only.
Q: A mod I use depends on BSL. Will it work with MDL3? A: Generally yes. But do not deploy BSL itself at the same time.
Q: Will it still work after a game update? A: Mod management usually keeps working. Data Hub needs to be updated by the author; until then it shows unsupported and stops reading.
Q: Can I include MDL3 in my modpack? A: Not without written permission. Please link to the official release page in your modpack's description instead.
Q: Can I get banned? A: The author cannot guarantee that you won't. Please read Section 8 and decide for yourself whether to use MDL3.
This page is part of MDL3 and must be provided with MDL3 in full and unmodified. The version on the official release page prevails.
