We have a special guide for you from a fellow player explaining how he mastered the learning curve of Battlefield 4.
Said player was frustrated with doing the right things for the team, but always finding himself the worst player in a session, with a negative K/D spread and a propensity for getting killed often. And then, he started playing differently, and started getting insights on frequent mistakes beginners make or take for granted.
First off, from a temporary respite from supporting the team, he learned the ins and outs of every map and realized that situational awareness is a key skill in Battlefield. In other words, you need to have an idea of the different angles found in the map, so you know where to take cover, where you are prone and where you are most secure at any time in the game.
His second insight is that the opposing team tried to accomplish objectives relatively consistently. This is a quirk of human nature, and one you can take advantage of easily. Armed with knowledge of the game map, you can predict to some degree where the enemy will be coming from. Essentially, success in this game boils down to knowing where the enemy is, and the best way to figure that out is to know the maps.
As you play some more, you will start to develop a sense of which angles you are vulnerable from, at a particular point in the game, and at a certain point in the map. Subsequently, you will learn to cover up these vulnerable spots better, and not rely on camping to stay safe. On this end, you should not hesitate to get help from a teammate to cover your back.
Lastly, you will have to acknowledge and study the best places for you to spawn. This decision could make the different between you being a competent player and a good one. You will have to make use of your other newly learned skills to make this decision, but if you’ve been playing smart, you will be smart enough to figure this out too.
