L2Solo (C4: Scions of Destiny)

Old-school Lineage 2 solo play, locally in a live world with over 1500 bot population.

🎮 Wanna play now?

You will need:

• Node.js 22.5+
• A Lineage II C4 client using protocol 656

Quick Start

npm start

That command will start the L2Solo Launcher.

Press Start in the launcher to run the server.

Configuration

Committed defaults live in config/default.ini.

Private local overrides go in ignored config/local.ini. This is where API keys and a machine-specific SQLite path belong.

Example:

[OpenRouter]
enabled = true
apiKey = <your-OpenRouter-key-here>
model = openai/gpt-5.6-luna
partyRouterModel = openai/gpt-5.6-luna
debug = true

OpenRouter can also read the key/model from environment variables:

OPENROUTER_API_KEY=sk-or-v1-your-key-here npm start

In-Game Commands

• .admin - open the admin menu.
• .sell - sell all unequipped non-Adena items for 50% item value.
• .bot - open the party control panel.
• .botparty- search for bots around player location to join player party
• .botfriends - friend list and const party management
• .botstatus - show a bot overview panel.
• .botstatus <name> - show detailed status for a specific bot.
• .botpath / .botpath <name> - inspect bot movement, town-route waypoints, and geodata path diagnostics.
• .trade or /trade - open the bot trade window with the targeted SimPlayer, useful as a fallback to the native client trade action.
• .leave - dismiss all companion bots.
• .kick <name> - dismiss one companion bot.
• /invite while targeting a bot - recruit that bot as a companion.
• /dismiss <name> and /leave also work through the party request path.

Nearby bots also react to plain chat lines such as hi, follow, wait, hunt, heal, and buff.
