Sony have announced the PlayStation Plus games for September 2018.
For PlayStation 4 - PS+ subscribers will get Destiny 2 and God of War III: Remastered while PS3 owners get the 20th anniversary edition of Another World and QUBE Director's Cut.
It appears that Destiny 2 is already available for free on the PlayStation Store so it's either a glitch or has become available ahead of the other September games, so you can snap that one up immediately.
The full line up is as follows:
Destiny 2 (PS4)
God of War III: Remastered (PS4)
Knowledge is Power (PS Plus Bonus – PlayLink)
Here They Lie (PS Plus Bonus – PS VR required)
Another World – 20th Anniversary Edition (PS3 + PS4/PS Vita)
QUBE Director’s Cut (PS3 + PS4)
Foul Play (PS Vita + PS4)
Sparkle 2 (PS Vita)
The games can be downloaded or added to your library on Sept 1st.
