Perhaps the most surprising thing about Doom — a game defined by its speed and precision, not to mention its gleeful application of gore — running on the Switch is that it’s not surprising. It’s right there: Doom on the Switch. It’s the campaign, the enemy placements and behaviors, the arcade mode. While I didn’t play the multiplayer component, it will be available as a separate download for those who want it. It’s a modern, cutting-edge, game of the year-winning shooter and it’s running on a Nintendo handheld.

First things first: Bethesda isn’t sharing details on the frame rate or resolution, and for good cause. The answer is: Neither are as good as on the Xbox One or PS4, or the gaming PC you built to play it maxed out, so why supply the ammunition? While the console versions enjoyed a steady 60 frames per second — a feature that helped advance the game’s focus on speed and precision — the Switch version runs mostly* at a smooth 30 frames per second.
