Doom Eternal just got detailed with new footage and a presentation at Quakecon, finally fleshing out the anticipated sequel since its announcement at E3 in June. Despite the previous Doom game coming to Switch last year, not many people expected the sequel to launch on Switch, as well. Bethesda apparently delights in subverting those expectations.

The Doom Twitter announced after the presentation that Doom Eternal will launch on PC, PS4, Xbox One, and Switch. Bethesda’s wording of “will launch on…Switch” sure makes it sound like it’s day and date as the other versions. If that’s true, that makes the first simultaneous launch for a Bethesda title on a Nintendo system pretty much ever.

Panic Button, the studio which ported Wolfenstein II: The New Colossus, Doom, Rocket League, and Warframe to Switch retweeted the announcement, indicating they’re likely behind the port. That means the game will probably look graphically similar to last year’s Doom port.

Doom Eternal has a target date of 2019 for PlayStation 4, Xbox One, Switch, and PC.
