Sony historically releases a month's free PS Plus games on the first Tuesday of every month.
Last year, PlayStation Plus subscribers were awarded brand new releases for "free" the day they were released on several occasions.
In other words, there's an increasing precedent of PlayStation Plus' free games including day one releases.
A safer bet for Devolver Digital, the game's publisher, and Flying Wild Hog, the game's developer, is to get money upfront for Shadow Warrior 2, and then use the PlayStation Plus momentum to build some momentum for the release of Shadow Warrior 3.
Team Ninja gets some adverstisement ahead of its 2022 release Stranger of Paradise: Final Fantasy Origin, PlayStation gets their PS5 game for the month, and subscribers get one of the highest-rated PS5 games.
