Get ready to dive into Yggdrasil and take part in a massive war
ATHENA: Blood Twins is a dark MMORPG set in the shattered world of Yggdrasil, delivering a unique worldview with immersive gameplay. In this game, you play as Warriors of Fate, tasked with fighting in the war that determines the world’s destiny as Athena, the Goddess of Wisdom, falls into despair.

I am excited about the ability to freely switch between the four unique classes, Warrior, Mage, Archer, and Cleric, at your will. On top of that, you can level up to even more advanced classes, unlocking new combos. You can summon powerful heroes and also customize your combat style.
The fast-paced 3-minute battles also look fun to me, packed with rich PVP gameplay. Whether it’s huge GuildvGuild battles, facing world bosses, cross-server Apex Duels, or open-world PvP, there’s so much to enjoy. And if you are competitive like me, you can compete with players and battle for global rankings.
