NERIUM

An Asian-fantasy MMORPG

Mist-wrapped peaks, forgotten shrines and endless war between rival clans. We are building our own online world — from the first line of server code to the last brushstroke of the interface.

The studio

An independent studio building a world of its own

Nerium Studio is an independent game studio based in Warsaw, Poland. We are a small, focused team creating Nerium — a full-scale MMORPG — without off-the-shelf MMO templates or engines bought by the kilo.

Every system is ours: the authoritative game server, the network protocol, the Unreal Engine 5 client, the interface, visual effects and the tools we use to build and run the world. AI-assisted development with Claude Code lets our small team move at the pace of a much larger studio.

The game

Nerium — where skill decides

An online RPG built around rivalry, teamwork and a world shaped by its players. Inspired by the legends of the Far East, full of monsters, ancient temples and clan warfare.

Open-world PvP

Fast, demanding player-versus-player combat where reflexes and tactics matter more than gear alone.

Guilds & clans

Found a guild, forge alliances and fight for dominance over the land together with your friends.

Player economy

Trading, market stalls and items whose value is shaped by the community, secured by the server.

Character growth

Levels, skills, equipment upgrades and a seasonal pass that rewards every evening in the game.

Bestiary & bosses

Dozens of monsters, dungeons and powerful bosses waiting for those brave enough to face them.

Built-in voice chat

Talk with your party and guild directly in the game — no third-party tools needed.
