PlayStation has posted the September lineup for PS Plus Extra and Premium. Ten games, staggered through the month, with two big ones on 15 September and the rest following weekly.
15 September: RuneScape Dragonwilds (PS5), the survival-crafting spin on RuneScape, and WWE 2K26 (PS5), this year's wrestling game and a fairly big get for the catalogue. Premium members also get Mega Man X Command Mission (PS5, PS4) and Metro Redux (PS4) on the same day.
Date Everything!, the dating sim where you romance your household objects, is already in for US and UK members from 9 September. 22 September brings Ball x Pit (PS5), the brick-breaker roguelike that did very well on PC and Switch, and Slitterhead (PS5, PS4). Then on 29 September it's Ninja Gaiden: Ragebound (PS5, PS4), Dungeons of Hinterberg (PS5, PS4) and Sniper Elite: Resistance (PS5, PS4).
The dates above are the ones PlayStation lists for the US and UK. Sony's blog notes lineups can differ by region, and Australia has historically followed the US and UK schedule, but check the PS Store on the day if one of the later ones matters to you.
