I’m a huge Doom (1/2/3/2016) fan but I’m not sure how I feel about this. Eternal just seemed like more or the same so I never even bothered playing it. The Dark Ages is starting to feel a little too Anime and just outside the whole space-based Doom universe. This just doesn’t seem like Doom to me and the gameplay looks like more of the same basically from the trailer.
I haven’t tried it personally, but Mox looks like a nice modern mailserver. It might do what you want.
