I don't think big companies know how to make a good FPS campaign anymore, let alone hone in on classic deathmatch multiplayer. The last FPS I bought was Half-Life: Alyx four years ago, and the first one to come along and interest me since then was Phantom Fury, but I'm letting that one iron out bugs for a few weeks before I pick it up. Even former TimeSplitters devs, given the opportunity to make a new TimeSplitters, made another Fortnite instead. Likely this new Perfect Dark was built to turn it into a live service that keeps players playing it forever rather than just making a fun deathmatch to play with your friends a handful of times, which would be missing the point. And all this is to say nothing about how those devs must be feeling when even a great game that sells well won't save you from Microsoft laying you off.
