Unlike most FPS shooters, Battlefield 1 won't put you in control of some genetically engineered super soldier. You'll be controlling a volunteer auto mechanic who's getting his first experience with a modern tank in the midst of battle. According to the game's blog you'll also travel with Lawrence of Arabia, follow two brothers who ship off together, and more. The campaign of Battlefield 1 will tell multiple stories that humanize the people who thought in World War 1.
In doing so, DICE believes they can give the player better immersion as opposed to just dropping their generic character in the war...
In previous Battlefield iterations we’ve experienced the story through the eyes of one main character, and it was very rare that the camera cut anywhere. But in Battlefield 1 we decided we wanted stronger characters instead of just telling players “you are the character”. One way to do this was to invoke classic cinematics that lets you see your character more than in first-person-theater. We wanted the player to see and feel what the characters are going through, rather than just experiencing it from behind their eyes. That has really payed off for us not just in storytelling ability, but in emotional engagement.
As for the gameplay of these campaigns, sounds like the same old campaign experience, which I can't complain about. I'm just happy we will be getting some more story besides blood and guts with over the top swearing every couple minutes! I also like the idea the campaign will be split between different characters and not pretend like one character is supposedly on the front lines of every major battle. Sounds like a good move don't you think?
