During the Google GDC 2019 keynote, company VP Phil Harrison revealed a new cloud gaming streaming service called Stadia. At a later point in the presentation, id Software executive producer Marty Stratton took the stage to announce Doom Eternal would be one of the games coming to Stadia.
Stratton said that Doom Eternal both plays and looks "great" on Stadia. The sequel to 2016's Doom will play in true 4K HDR at 60 FPS on the cloud gaming platform. Stadia itself is designed to unite players, spectators, and developers all on one platform. For example, during Google's keynote, the company showcased how you will be able to watch a trailer for a game on YouTube and then start playing said game through streaming within a few seconds.
Stadia will also feature cross-platform support. Harrison confirmed cross-platform play, allowing you to play with others regardless of platform. Stadia will also support cloud saves for game state and save files, so specific titles could have cross-platform progression as well.
Stadia will be supported across several platforms, including desktops, laptops, TVs, tablets, and phones. At launch, the service will be able to stream games up to 4K HDR at 60 FPS with surround sound, and Google has scheduled plans to increase that to 8K resolution in the future. Although you can use existing controllers with Stadia, Google is also releasing its own controller--which supports Google Assistant. Stadia scheduled to release sometime this year.

Doom Eternal is also loosely scheduled for 2019, coming to Xbox One, PS4, PC, Nintendo Switch, and now Stadia. Neither Bethesda or id Software has announced whether the game is coming to the Switch the same day as the other platforms, or if that version will be delayed. Eternal is more immersive and gruesome than its predecessor. The new game also offers additional means of moving around the map--including a grappling hook and free running.
