I bet it'll be rather powerful, actually, with a fire rate of two hundred and forty rounds per minute with a twenty round magazine.
Unfortunately, I don't think I'd get Battlefield 1, since it'll probably be a primarily competitive multiplayer game, but maybe it'll have some kind of PvE mode or something that'll catch my interest. Yet regardless, I think I'll keep my eye on it... since World War One is a rare sight in pretty much any game, and I think DICE will do a great job with this game
