Overview
IRONHAVEN is an Old School RuneScape-inspired MMORPG built entirely in Java 21. Not a mod, not a clone — a ground-up reimagining of the tick-based, isometric 2D MMORPG formula that defined a generation of online gaming.
The architecture is serious: a custom 256-tick game loop server built with Netty, Protocol Buffers for network serialization, and LibGDX handling the client-side isometric rendering. Designed to handle real persistent world state from day one.
IRONHAVEN takes the best of OSRS — meaningful skill progression, rewarding exploration, player-driven economy — and builds a new world around those principles.
