Played for a number of hours. Framerate on Xbox One is poor. Visuals are a huge upgrade over BF4, but still very soft looking because of 720p. Jaggies are not that pronounced.
Lots of bugs right now, especially in the menu. Try to stay out of the start menu on Xbox One, and don't bother changing your visual settings because they'll reset at the start of every match.
War Tapes setting for audio is great.
Lots of nice touches, like not being able to use iron sights while wearing a gas mask. The "power ups" like flamethrower are an interesting addition.
Map is pretty good, but not one of my favourites I've played in a Battlefield game. It is pretty good though. The biggest downside, or maybe design problem I've seen in the game mode is that the train basically doesn't contribute much of anything. I'm not sure how it spawns, but so far I haven't seen a train really impact the game.
Conquest still plays like conquest. My squad basically rolled top squad every game and the basic Battlefield play style still works/wins.
The overall controls feel like BF, but the guns are much looser and have biggest strengths and weaknesses. A lot of the faster firing weapons are very loose and have poor accuracy over distance. You can't snipe with smgs and lmgs like in other additions of the game. That does seem to favour a ton of people playing sniper, but so far my squad has never rolled one and we're always top and usually win. Sniping is the way to try to sit back and accumulate k:d ratio while losing. Purchasing a few of the weapons available is a good idea as they're better than the default ones.
Had a pretty good time playing it tonight.
