Diablo 4 is set to join the PlayStation Plus lineup for July 2025. The game was released back in June 2023 across multiple platforms and saw a successful launch. It is an ARPG title set in a grim fictional world called the Sanctuary, where you face off against the forces of hell unleashed by Lilith. This announcement comes less than a week ahead of the Season 9: Sins of the Horadrim update. It is one of three games being added to the PS Plus lineup. Players will be able to enjoy the campaign and decide if they want to go for the Vessel of Hatred expansion.Diablo 4 to join PlayStation Plus ahead of Season 9 updateSins of the Horadrim is less than a week away (Image via Activision Blizzard)With a new season approaching, the decision to include Diablo 4 for all PS Plus members is a great move to bring in more players.
