Unannounced Id Software Game Spotted Being Rated In Australia

The odd title might look familiar for those who've been following id Software's projects lately. It's similar but different from Project 2021A, which was also leaked back in January via another Classification Board website. Project 2021A is also an unannounced game that will be published by Bethesda and is not the same as Project 2021B.
