This year’s Call of Duty: Call Of Duty: Modern Warfare will not resort to peer-to-peer (P2P) solutions in multiplayer.
Infinity Ward’s Call of Duty: Modern Warfare will push the cross-play between the PlayStation 4, the Xbox One, and the PC with dedicated servers, so the following scenario will not happen (and neither will the case of connecting to each other): you join a match, the host gets bored, quits the game, and the entire match goes into the proverbial toilet followed by a flush. Activision Blizzard will provide servers for the players, which sounds good on paper, but practically, the quality of the multiplayer will depend on the number of available servers, and aside from it, the quality of the netcode will also be a question mark altogether in 2019’s Call of Duty. We’re probably still going to see the first-day server issues…
Previously, we discussed how the cross-play will put you together with people using the same peripherals. If you use the keyboard and the mouse, you get to compete with others using these devices, and if you use a controller, you can opt-in to face keyboard+mouse players if you want to. (The game will lock in your device at the start of the match, so you can’t switch during it.)
Rolling this out to consoles: the Xbox One already has system-level support for keyboard and mouse, so those who own Microsoft’s console can easily turn it to a semi-PC in Infinity Ward’s game. What about the PlayStation 4? Joe Cecot, the multiplayer design director, has written the following on the PlayStation Blog: „One of the main ways is that we are planning on matchmaking based on peripheral. We’re also supporting different peripherals, so if you want to plug a keyboard [and mouse] into your PlayStation 4, you can.” So the PS4 might not be in a disadvantage against the Xbox One.
Call of Duty: Modern Warfare is out on October 25 on PlayStation 4, Xbox One, and PC.
