Well this is a big one. Destiny 2 for the PS4, released last year, is now free for active PS Plus subscribers in September. The loot-shooter had a lot of hype before its release and sort of fizzled out afterwards.
A new expansion, Forsaken, is launching September 4th so this is most likely a ploy to get interest back for that too.
Outside of that, God Of War III Remastered is also available for the PS4. Apparently this game was already offered last year in Asia, so this is the rare instance the same game is offered again in the free games collection.
Unique for Asia however is Zero Escape: Zero Time Dilemma for the Vita and Soul Calibur V for the PS3. Another World: 20th Anniversary Edition rounds up the list for Asia.
These games will be available for download starting September 6th until October 3rd.
