Square Enix has just released a patch for Lightning Returns: Final Fantasy XIII's PC version. Marking the third entry in Final Fantasy XIII's trilogy, that arrived on Steam back in 2015, making it rather surprising that they've issued an official update after so long.
Released yesterday, it's a rather minor update that states the following:
Thank you for your continued support of LIGHTNING RETURNS: FINAL FANTASY XIII. An update of the game has been implemented as of 12th July 2021.
Update Content: Fixed an issue of Lightning’s voice not being played in some scenes.
Lightning Returns: Final Fantasy XIII Gets Surprise Patch Six Years After Launching
While that's great to see this issue fixed, it wouldn't be a notable patch at all if not for the timing. After all, why update a game out of the blue after six years? Admittedly this is speculative, but the likely answer is due to Xbox Game Pass. Square Enix already has multiple entries on Microsoft's subscription service and back in 2019, Final Fantasy XIII's trilogy was confirmed to be joining.
As such, this Steam update could be preparing the PC edition for that Game Pass launch. While it's been nearly two years since that announcement, Microsoft confirmed to TrueAchievements back in January those remaining Final Fantasy games are still coming.
