Age LAN Server

Age LAN Server (formerly AoE 2 DE LAN Server) is a web server (with its launcher) that allows you to play multiplayer lobbies without having an internet connection to the game server ensuring the game multiplayer functionality is still available even if the official server is in maintenance or is eventually shutdown.

Note: It is not strictly limited to LAN only.

Important

You will still need a custom launcher to bypass the online-only restriction that is imposed by the game to being connected to the internet and Steam or Xbox Live, depending on the platform and version, to fully play offline. My other project provides the files and information to download a Steam Emulator and play 100% offline.

Unimplemented features

List of unimplemented features

• ❌ Matchmaking: does not make sense having a likely ephimeral server with limited users, use the official server for that.
• ❌ Achievements: only the official server should be able to. Meeting the requirements of an achievement during a match might cause issues (see Troubleshooting for more details).
• ❌ Changing player profile icon: the default, or empty, will always be used.
• ❌ Leaderboards: will appear empty.
• ❌ Player stats: will appear empty.
• ❌ Clans: all players are outside clans. Browsing clan will appear empty and creating one will always result in error.
• ❌ Lobby ban player: will appear like it works but doesn't.
• ❌ Report/Block player: will appear like it works but doesn't.

Note: Most of these do not apply to Age of Empires: Definitive Edition.

Minimum system requirements

Note: If you are using Antivirus it may flag one or more executables as virus, this is a false positive.

Verification

The verification process ensures that the files you download are the same as the ones that were uploaded by the maintainer.

Verification steps

1. Check the release tag is verified with the committer's signature key (as all commits must be).
2. Download the ..._checksums.txt and ..._checksums.txt.sig files.
3. Import the release public key and import it to your keyring if you haven't already.
4. Verify the ..._checksums.txt file with the ..._checksums.txt.sig file.
5. Verify the SHA-256 checksum list inside ..._checksums.txt with the downloaded archives.

Exceptions on tag/commit signature:

• Tags:
  • v1.2.0-rc.5: mantainer error.
• Commits:
  • 631cfa1 through 9eb66cf (both included): rebase and merge PR issue.
  • 55697d4: rebase of dependabot.
  • feb28de: partially verified due to dependabot.
  • d2b1749, 82ca9f1 and baa75ce: merge mistake.

Installation

Both the launcher and server work out of the box without any installation. Just download the archives, decompress and run them.

How it works

Server

The server is simple web server that listens to the game's API requests. The server reimplements the minimum required API surface to allow the game to work with lobbies. NO data is stored or sent via the internet.

Note: See the server README for more details.

Launcher

The launcher allows to easily play the game in lobbies while still allowing the official launcher to be used for online play.

Features

• Automatically start/stop the server or connect to an existing one.
• (Optional) Use an isolated metadata (except AoE I) directory to avoid potential issues with the official game.
• (Optional) Modify the hosts file to:
  • Redirect the game's API requests to the LAN server.
  • Redirect the game CDN so it does not detect the official game status.
• (Optional) Install a self-signed certificate to allow the game to connect to the LAN server.
• (except AoE I) Add a certificate to the game's store to allow the game to connect to the LAN server.
• (Optional) Run custom configuration commands to setup/revert the configuration.
• (Windows Optional) Re-broadcast the battle server through other network interfaces apart from the most priority one.
• Automatically find and start the game.

Afterwards, it reverses any changes to allow the official launcher to connect to the official servers.

Note: See the launcher README for more details.

Simplest way to use it

1. Download the proper full asset from the latest stable release from https://github.com/luskaner/ageLANServer/releases.
2. Uncompress it somewhere.
3. Windows Optional: You may need to add the launcher/server binaries to the exception list of your Antivirus.
4. Windows Optional: Unblock the .exe files as explained here
5. If not using the Steam or Xbox launcher, edit the launcher/resources/config.<game_title>.toml file with a text editor (like Notepad) and modify the Client.Executable section to point to the game launcher path. In this case, you also need to modify Client.Path to point to the game's directory. You will need to use a custom launcher (plus what my other repo provides) for 100% offline play.
6. If you are using AoM and don't have AoE II: DE installed on Steam edit the battle-server-manager/resources/config.athens.toml file and point Executable.Path to the AoE II: DE BattleServer.exe executable (it's portable), for example, 'S:\SteamLibrary\steamapps\common\AoE2DE\BattleServer\BattleServer.exe'.
7. Execute launcher/start_<game_title> script: you will be asked for admin elevation and confirmation of other dialogs as needed, you will also need to allow the connections via the Microsoft Defender Firewall or any other.
8. Repeat the above steps for every PC (except the point 6) you want to play in LAN with by running the launcher, the first PC to launch it will host the "server" and the rest will auto-discover and be prompted to connnect to it.
9. In the game, just host a new lobby via the Multiplayer section. Setting it to public visibility is recommended.
10. If the lobby is Public, they can join directly in the browser or you can Invite friends by searching them by name and sending an invite as needed. If the game allows, you can share the link to join the lobby automatically (only works if already in-game).

Standalone execution

Server instructions

1. Download the proper server asset from latest stable release.
2. Generate the certificate by simply executing bin/genCert.
3. If needed edit the config file.

Launcher instructions

1. Download the proper launcher asset from latest stable release.
2. If needed edit the launcher/resources/config.<game_title>.toml and/or launcher/resources/config.toml files. You will need to edit the Client.Executable section to point to the game launcher path if using a custom launcher which you will need to use a custom launcher for 100% offline play.
3. Run the start_... script.

Note: If you have any issues run the bin/config revert -a.

Battle Server Manager instructions

1. Download the proper battle-server-manager asset from latest stable release.
2. If needed edit the battle-server-manager/resources/config.<game_title>.toml.
