Better keep ripping and tearing because it's still not done.
DOOM Eternal Ancient Gods P1

DOOM Eternal: The Ancient Gods - Part One is now available on the Xbox One, PlayStation 4, PC, and Stadia. This release is available for those that own the Deluxe Edition of DOOM Eternal or the Year One Pass for the game. It is also available as a separate standalone release that also includes access to Battlemode. That is to say, you do not need to own the base game of DOOM Eternal in order to play The Ancient Gods - Part One.

The Year One Pass is available currently for the price of $29.99 (USD). Alternatively, The Ancient Gods - Part One on its own is $19.99 (USD). I think it would be safe to assume then that Part Two, whenever that comes out, will also be $19.99, thus making the Year One Pass a more attractive offering if you know you'll want to play it all.

What follows is a bit of spoilers for the end of DOOM Eternal and the start of The Ancient Gods. Tread lightly.

After defeating the Khan Maykr and obliterating the reincarnated Icon of Sin, the DOOM Slayer’s fight is just getting started. Unleash your vengeance and face your greatest test as you march back to the Maykr’s realm. Defeat powerful new threats, restore order to the heavens and unearth the corruption that has thrown the universe into chaos.
