That's neat but at that point I would rather be at my desk than on a couch and trying to figure out how to situate a mouse and keyboard. Pretty sure the new cod has cross play. I don't technically play a lot of multiplayer either. I usually get to level 50 or whatever and then play the campaign and call it done after that.
With God of war, Callisto protocol, and dead space coming in the next couple months i dont see myself sticking to cod much longer.
The XIM apex is what I use to play M&K at my desk with my Series X and it's worked great with my PS4pro and previous gen consoles. Last I checked it does not work well with the PS5, though some are trying to crack that.
But for the XBox and previous gen Playstations it's fine,. It's not being produced by XIM anymore for really any good reason but they are sometimes found on the secondary market. It is by far the absolute best M&K translator. There are certain games it does not work good such as with Halo where the turn speed is so limited that it can't translate turning very well no matter what you do. But for most FPS it works great - COD and BF games included among many others.
I'm 47 and controller players can kick my ass. I used to be at the top in a lot of PC lobbies when I played Halo and BF games in my twenties and thirties, but as you get older, you can't compete with reaction times with 16 year old gamer kiddies. But I can play well enough today to have fun in competitive pubs.
If you aren't into multiplayer FPS then it's not so important, though a lot of XIM folks seem to use it for singleplayer games. But to me I can't beat the thrill of playing a competitive match against other folks in good FPS multiplayer games.
