This actually was ok even though BN4 was total garbage.
Anyways, there is a new mode called "liberation" missions where its like turn-based strategy, but In my opinion, it didn't live to the hype. It was more like a total annoyance. But still having the ability to control other navis is pretty fun.
Above all else, theres really nothing to add. Same old stuff, same old dumb darkchips, same old dumb characters, same old dumb weaponry, and somewhat dumb storyline. Theres really nothing much to add.
If you're a fan of the series, give this a try, but I dont recommend it as much. If you want to save money, try to avoid this. If you want to play it a bit, rent it first.
