One thing, in particular, highlighted in the first round of previews - is the fact this game is a "strictly campaign" affair. In other words - don't expect multiplayer to feature. Here's exactly what Marty Stratton had to say about this ( via Eurogamer ):

Pre-orders for Doom: The Dark Ages are still nowhere to be found at Walmart. But the big retailer is pretty good with making sure every big game of the year it represented, so we're betting it won't be long until the pre-order PS5 and Xbox Series X copies of the game make an appearance.

Dark Ages also features a bunch of difficulty sliders that will let you change how fast and hard the game is, making it easy for everyone to hop in and kill demons. Doom: The Dark Ages arrives on Xbox, PlayStation, PC, and Game Pass on May 15.
