Terasology is a game that pays ample tribute to Minecraft in initial look and origin, but stakes out its own niche by adopting the NPC-helper and caretaker feel from such games as Dwarf Fortress and Dungeon Keeper, while striving for added depth and sophistication.

Terasology is an open source project started by Benjamin "begla" Glatzel to research procedural terrain generation and efficient rendering techniques in Java using the LWJGL. The engine uses a block-based voxel-like approach as seen in Minecraft. After proving itself as a solid tech demo begla was joined at first by Anton "small-jeeper" Kireev and Rasmus "Cervator" Praestholm and a full-fledged game concept was born.

The creators of Terasology are a diverse mix of software developers, game testers, graphic artists, and musicians. Get involved by checking out our Community Portal, our blog Moving Blocks!, and our Facebook Page.

Terasology is licensed under the Apache 2.0 License and available in source code form at GitHub.


Terasology requires the latest version of Oracle's Java Virtual Machine (JVM). Also make sure that your graphics card driver is up to date.

Download the latest stable version here or our cutting-edge develop version here from our Jenkins

You can use one of the default launch scripts to start the game. The scripts will setup your JVM to allocate up to 1024 MB of heap space. Under Linux and Mac OS X the run script needs the access permission "Execute" to run properly: "chmod +x".
