The Polish website boop.pl has published information about the upcoming stage of closed beta testing of Valorant's first-person multiplayer first-person shooter. If you believe the source, then this stage will begin on April 7th.
Streamers will get guaranteed access, and the rest will be able to receive an invitation by submitting an application on the official website.
Also, as stated on the same Polish site, all progress with the CBT will be reset, but players will be able to make in-game purchases for real money.
