Sony originally revealed that the month of July would consist of Pro Evolution Soccer 2019 and Horizon Chase Turbo for all PS Plus Subscribers, but with an interesting turn of events, you are getting more than what you bargained for.
The last minuted decision was made by Sony to change Pro Evolution Soccer 2019 and to rather give away Detroit: Become Human. To sweeten the deal even more, Detroit: Become Human will be the Deluxe Edition version which means you will also receive your copy of Heavy Rain. Horizon Chase Turbo will still be included in the package for July on top of this!
Here is a response regarding the sudden last minute change from Sony:
These games are available now on the PlayStation store and waiting to be added to your game library. This is really a great and unexpected surprise by Sony changing up the give away titles for July 2019 because maybe some companies do listen to their loyal supporters?
