EA has shared details on Battlefield V's first closed alpha. The limited-time test began on Thursday, June 28, and allows certain players to try out the upcoming World War II shooter ahead of its release later this fall, including a portion of one Grand Operation.

According to Battlefield's official website, the closed alpha will be available on PC and can only be joined by invitation, which EA says were distributed to a "small group" of Battlefield players. The invitations will contain a code to download the alpha client, which must be redeemed via Origin in order to get in.
