2D RPG base game client recreated in modern HTML5 game engine with AI
When I was much younger, I used to play a Korean MMORPG called Helbreath, and I also hosted a bunch of private servers for it. I eventually moved on, but I always loved the game’s aesthetics, its 2D nature, and its atmosphere. That may just be nostalgia talking. The community maintained private server and client, which to my knowledge were based on leaked official files, were written in fairly archaic C++. If you’re interested in the original sources, I’ve included the main client and server files, Client.cpp and Server.cpp, in the reference folder. I always felt that if the project was…
2D RPG base game client recreated in modern HTML5 game engine with AI launched on March 10, 2026 with 11 votes, #1,113 of 23,380 launches that month and more than 90% of that year's launches.
In plain words
This project recreates a classic Korean 2D MMORPG client in modern HTML5 using a contemporary game engine, replacing legacy C++ code. Built for players nostalgic for the original game's aesthetics and atmosphere, it aims to preserve the title's 2D nature while leveraging modern development tools for better structure and expanded possibilities. The creator has included original source files for reference, enabling community contributions to a newly architected version of the beloved multiplayer game.

Browser based MMORPG base game built in JS/TS (client) and C# (server) - ErkoKnoll/helbreath-base-game
Helbreath Base Game is a browser-based recreation of the classic Helbreath client, built with Phaser 3 and React , paired with an authoritative multiplayer game server written in C# / .NET 10 that communicates over WebSockets with Protobuf messages. It is designed as a foundation for building 2D (MMO)(A)RPG-style projects and is best thought of as a playable base client + server or lightweight game framework rather than a complete game. The project has been developed heavily with AI assistance and is intentionally kept approachable for AI-assisted workflows and iterative expansion.

I've posted this game here before, hopefully a repost is fine as the game has changed quite a bit (improved AI, improved mapeditor, much quicker gameplay, etc). Game is based on JavaScript/Canvas and WebSockets. On the browser side the map is pre-rendered (as a background image), just the mobile units/buildings and animations are dynamically rendered. The lobby server is made in node.js, but the game server is C++ for performance reasons (mainly the pathfinding). I found the C++ WebSocket libraries out there to be too difficult to use so I made my own based on the rfc. Overall I…

I've been working on an MMORPG that is now in alpha as a solo developer. Here are the major open source technologies that I use: Blender - 3D modeling software for creating the overall environment and every game object. I've gotten a lot of CC and Public Domain assets from https://poly.pizza GLTF - I export assets from blender to the GLTF asset format JSON - I write a JSON config for every game object that describes things like its name, its interactions, its collisions, etc. Node.js exporter - I iterate over the environment and every asset to create a scene hierarchy. I use…
I'm open-sourcing my game engine2023 · github.com · ▲318Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev. We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games. I hope some of you guys will find this useful. Would love to hear feedback also. Thank you. Engine Demo: https://www.modd.io

Hi, I've been developing an HTML5 MMORPG game where people can submit code to play a game, like collect items, destroy defense towers or kill monsters, etc.. I've been working on this for over 1.5 yrs (all my spare time) and now it's ready for preview, does anyone want to try it out? It's mostly opensource (and the rest will be opensource sooner or later) Please access it with PC, it's an HTML5 game: https://bytelegend.com/ I really want it to expand to more languages, but right now I've only finished Java part. I wonder if anyone can help me with other languages. Besides, I'm…

Hi HN! 2d spritesheets for game development are often distributed as a PNG image, sometimes with a separate JSON or XML metadata document describing the layout, including any animation sequences within the sheet. Sometimes there is no metadata document and you have to work it out and manually write custom code to chop up the spritesheet and reference the sprites you want. I think it would be good if it became standard practice to distribute spritesheet PNGs with the metadata inline inside a PNG "chunk" so the whole thing is self-contained. That way artists can just distribute one file, and…
