According to a report from Forbes, cross-play for this year's Call of Duty game between has a bit of a catch in regards to PC players.
Its not a pure PC vs. Xbox/PS4 but works more similar to Fortnite.
If a PC player uses a controller, they automatically get paired with console players. If they use a keyboard & mouse, they only get paired with other k&m PC players. Its possible for console players to play against k&m PC players but requires them to opt into those matches since matchmaking won't do it by default.
Those restrictions on k&m PC players don't apply for party groups.
Also its unknown if PS4 players will be restricted to matches only against PS4 players whenever a DLC pack gets released regardless if they bought it or not due to Sony's 1-week exclusivity for them.
