“With E3 2021 finished and our Update 6 just released, we want to provide you an update on our latest work and plans for DOOM Eternal in the months ahead.
In March, we marked DOOM Eternals one-year anniversary with the release of our second campaign expansion, The Ancient Gods Part Two. Together, both of The Ancient Gods expansions deliver some of the most engaging and exciting gameplay the series has offered, as well as an epic conclusion to the Slayer saga that we began in DOOM (2016). The Ancient Gods Part One is also now available for Nintendo Switch and we expect to release Part Two later this year.”
