War mode is the big addition to Call of Duty multiplayer this year – a hybrid that throws in narrative objectives, Overwatch Payload, Call of Duty Zombies and Battlefield 1’s Operations. Play across a map shifts as teams complete objectives; attacking or defend an outpost, building a bridge and escorting a tank, obliterating an enemy bunker. It gives a full squad of players a real focus and sense of purpose, putting teamwork front and center. That determined push to advance as a united (6v6) force will be what wins the day.
Good vid explaining what war mode is like below with gameplay.
This really does look like BF1 all over. So from that angle, this game could really fly. Mainly down to if its comparitive gameplay but with a CoD name, not Battlefield, it will get soaring reviews.
