During today's livestream, and also a pre-brief we viewed yesterday, EA revealed that Battlefield 5 will include a 4-player co-op mode.
The last time we saw co-op in Battlefield was in Battlefield 3's 2-player campaign. Battlefield 5's co-op won't be quite the same. Called 'Combined Arms,' it will drop up to four players into bot matches with "a wide variety of missions" to accomplish.
