A fearsome new threat is coming very soon to Monster Hunter World. Capcom has announced that the Elder Dragon Lunastra will be added to the co-op action RPG, and she'll arrive alongside a new set of gear and other content in a free update tonight, May 30.

Unlike the recently introduced Kulve Taroth, Lunastra is a returning Elder Dragon, originally appearing in the series' 2006 installment, Monster Hunter 2. Known as "the Empress of Flame," Lunastra is the counterpart of Teostra, and she can fight alongside her mate and "bond" with him to unleash powerful attacks.
