Developed by Teos Games LLC
TEOS ONLINE is a fantasy MMORPG set in the world of Erinoth, developed, published and operated by Teos Games LLC since 2022.
Our own engine gives us full flexibility: we build exactly what TEOS ONLINE needs and tune every part of it for maximum performance.

Since 2022 the game has grown with thousands of changes: new systems for models, animation and worlds, and new content with every update.
