Adventure Land: The Code MMORPG

Adventure Land: The Code MMORPG is an open-source MMORPG set in a shared world where you fight monsters, find gear, explore and build a party that can run JavaScript CODE. You can play manually or use the working default CODE without programming experience, then edit it a line at a time to automate tasks and develop routines for your characters. Your characters, items and CODE persist without seasonal wipes, and you can join other players at bosses and events while building your own collection.

Build and automate your party

You control up to four characters at once: three adventurers and a Merchant. Choose from Warrior, Paladin, Rogue, Ranger, Mage, Priest and Merchant, and combine their skills and equipment to shape your party. For example, a Priest can keep fighters alive, a Paladin can protect them, and a Merchant can sell loot. Each character can run its own JavaScript and communicate with the others, and you can also form a party with other players.

With the built-in editor and documented JavaScript API, you can automate a potion, then teach your party to travel, select targets, heal one another, manage equipment or trade. You can inspect what happens, adjust the code and send the party out again in the live world alongside other players' characters and CODE. A tutorial includes a JavaScript Crash Course, and you can connect a compatible AI through MCP (Model Context Protocol) to read guides and live game data, inspect characters and equipment, and help write, test and improve JavaScript.

Develop your characters

Early levels come quickly; later progress includes rare finds, ambitious crafts and party setups to keep improving. Characters develop through levels, equipment, upgrades, compounds, crafting and learning how their skills work, rather than skill trees. There are bosses to fight cooperatively, PvP, and farming spots where you can hunt while your Merchant runs the shop.

Equipment can be upgraded and accessories compounded, while recipes send you in search of materials across the world. You can gather ingredients yourself or trade for them. Players buy and sell items, including direct item-for-item trades, so loot your party does not need may be useful to someone else. Your Merchant can also fish or mine while the rest of the party hunts; different locations offer different finds.

Explore the world

The Progression Guide examines your character and equipment and suggests farms, gear projects, and places to find needed items and materials. Nearby INFO links at NPCs, services, gathering spots and dungeon entrances open guides that explain how to play manually, then provide CODE instructions and examples for automation. Wizard and the community continue to add explanations of the game's features.

In the Cave of Many Dreams, take up to three characters on a daily adventure, with one run per account. You can rescue a traveler, hire help or take a side in a fight. Bring your own equipment and keep the loot you earn; dying inside costs no XP, gold or items. Other activities include dice and a slot machine in the Tavern, and Spooky Town, where an invisible statue has an unusual appetite for items.

You can visit the Citizens, follow seasonal events, collect cosmetics or find a use for items stored in your bank. During Halloween, you can face the Headless Horseman at midnight realm time, fight through graveyard waves and go Trick or Treating for equipment, cosmetics and the animated Sinister Laugh emote. Witch's Cipher has players collect ingredients and work together to solve a secret recipe using clues, logic or CODE. After Halloween, the puzzle continues as a rotating daily event.

Events and guides

The Events window lists active seasons, daily activities and events coming in the next seven days, using either local or realm time. You can set a reminder for an event and receive an in-game log notification 10 minutes before it starts.

Open-source and hosting

The client, server and game data are open source. You can examine how the game works, build a tool or custom client, and contribute improvements. CODE can run in the Steam client, a browser, on your own server or through a community client. Optional Mainframe hosting keeps your CODE running while your computer is off, and lets you check its logs when you return; running CODE yourself has no hourly game charge.
