This information and video was from the offical Valorant twitter, however it seems like this information about Astra was accidentaly released so Riot has now taken down tweet and the preview video of Astra.
What we know so far is that Astra is the 15th Valorant Agent and will be live to play 2nd March, with the release of Episode 2: Act 2.
The new agent looks amazing, and is able to stun enemies when they walk through her ultimate Viper wall, she can also pull enemies into a ring and put down smokes. Below you can find more detailed description of Astra’s Abilities.
ACTIVATE a Star to transform it into a Nebula (smoke).
ACTIVATE a Star to detonate a Nova Pulse. The Nova Pulse charges briefly then strikes, concussing all players in its area.
ACTIVATE a Star to form a Gravity Well. Players in the area are pulled toward the center before it explodes, making all players still trapped inside fragile.
Use (F) on a Star to Dissipate it, returning the star to be placed in a new location after a delay.
Dissipate briefly forms a fake Nebula at the Star’s location before returning.
ACTIVATE to enter Astral Form where you can place Stars with PRIMARY FIRE. Stars can be reactivated later, transforming them into a Nova Pulse, Nebula, or Gravity well.
When Cosmic Divide is charged, use SECONDARY FIRE in Astral Form to begin aiming it, then PRIMARY FIRE to select two locations. An infinite Cosmic Divide connects the two points you select. Cosmic Divide blocks bullets and heavily dampens audio.
Astra is an unreleased and upcoming agent to Valorant. Therefore we don't know yet about the agents ability costs, contract information & rewards. All information will be available at our website as soon as we know more, stay tuned!
