In terms of game modes, you will find the famous Conquest and Domination modes(which is like Conquest but on a smaller scale). None of that changes in Battlefield 4 because it doesn't need to – those are it's hallmark features. The style is unmistakable: it takes place in teams, divided into squads, requires quick but tactical activity, the use of vehicles, and gives a great feeling of playing on a giant battlefield. Multiplayer mode doesn't change much with respect to previous versions of Battlefield. And does it ever! Compared with the single player mode, the multiplayer mode is a completely different story. The multiplayer mode is the first choice on the menu, and this is where Battlefield 4 can flex its muscles. The fact that the single player mode is little more than an extra bit on the side becomes perfectly clear when you look at the main menu of the game.
If you were intending to buy the game for it’s single player mode, then you’d be better off looking elsewhere: the campaign lasts 4 hours and really isn’t worth it. There are lots of pre-programmed scenes, enemies with limited AI, absurd dialog, and scenarios that seem similar to other games. In Campaign mode, Battlefield 4 is a succession of levels that set out to impress the player.
