In addition to 18 eternal light weapons and a website-based leaderboard for heroes, the update will introduce (and skin) Zandora.
"A lance-wielding Eternal who has emerged from the Star City to walk among mortals, Zandora is a melee/support hybrid who uses auras to empower herself and allies on the battlefield. Zandora is already the second Hero released since the game’s Dec 8 Game Preview program live date, increasing the total cast to 18. With the goal of a new Hero every 6 weeks, the team is excited to massively grow the Hero pool, expanding the highly strategic play. Owners of Gigantic’s Founders Pack will automatically unlock Zandora for free."
A new creature and three additional skins will follow a week apart through the month of March.
