Second appearance of Steph Gingrich, who was introduced in Life Is Strange: Before the Storm (2017) and became a fan-favourite. Katy Bentz not only reprised her part, she also played the character in "Wavelengths", a bonus chapter of the game that was specifically written for her.
Some of the outfits in Alex' wardrobe are based on the ones worn by characters of the previous games.
The first game in the series that had a simultaneous digital and physical release. Previously, each game was released digitally and in episodic form, and the disc version came some time after all episodes were released.
