PS Plus has a free trial period to take advantage of the Extra and Premium plans for a limited time.
This option allows us to try the games for 7 days which gives us access to games like Stray.

PS Plus was launched as a good option for gamers to access PS4 and PS5 games or relive the past with PS1, PS2, PS3 and PSP games. This venture has left us with a catalog full of adventures that will keep us entertained for a long time, but PlayStation also wants us to explore the service with a free trial already available on their devices.
Because, as originally stated by the XGP environment (via VGC), users have access to a 7-day trial period to discover all the benefits of the Extra and Premium plans that allow us to play current and retro games. However, it is worth noting that this possibility does not appear for PS Plus members, so it may be limited for new users.
On the other hand, we’d like to leave you with more details to consider if we want to launch the 7-day free trial. In this sense, the platform challenges us. to choose a monthly, quarterly, or annual plan Before the trial period starts for the Extra and Premium models, we must not forget that we must enter the card number if we want to take advantage of this service promotion.
While we cannot avoid these obligations, PlayStation allows us to cancel the subscription at any time. If this has piqued your interest, note that we have prepared an article on 3DGames where we detail step-by-step how to opt out of PS Plus. However, if this first test convinced you, know that 3 free games of the Essential plan are now available for download, and titles reaching the Extra and Premium models have also appeared.
