It looks like The Last of Us: Part II is getting another PS4 Dynamic Theme today, to celebrate Outbreak Day. The new theme will apparently feature a "stylized Ellie", animated effects and music.

The Last of Us Part II

The theme has appeared on the Australian PlayStation Store, suggesting it will appear in further stores as September 25th continues. September 25th is Outbreak Day – the day on which the game's cordyceps fungus became unstoppable. Since 2013 Naughty Dog has used this iconic day in the game's fiction to celebrate The Last of Us with its fans, including releasing new details or digital merchandise. Last year, a theme celebrating the upcoming launch of The Last of Us Part II appeared on the Store; now that we know even more The Last of Us Part II details, Naughty Dog have come up with yet another new theme to download to your console. Here's the store description:

Honour the victims of the deadly cordyceps fungus infection with this free PS4™ theme.

Outbreak Day – 26 September – is when the infection hit critical mass and a state of national emergency was declared in Naughty Dog’s masterpiece, The Last of Us™.

Give your home screen a brand-new look with this theme featuring a stylized Ellie with animated effects and new music from The Last of Us™ Part II.
As Outbreak Day dawns around the world, we're certain that the theme will become more widely available in local regional stores.
