Familiars.io

Retro monster-catching comes to a shared online world in this multiplayer RPG .io game. Explore a large map, battle other trainers, and build a team of Familiars through turn-based combat that supports real online PvP.

Use BALL items to catch new creatures and add them to your roster. If a Familiar's HP hits zero, it is gone for good, so every fight carries real stakes. Items scattered across the field help you heal and prepare for tougher encounters.
