-) Don't land in the area with Point of Interest or hot spots like towns/new areas
-) Always stick together with your team, and don't wander off alone
-) Check your surroundings 24/7, and always listen to footsteps
-) Avoid conflict at all cost, and only attack for either retaliate the enemy attack, or when your team has the advantage
-) Build walls for cover the moment you saw an enemy is attacking you
-) And last but not least: Always communicate with your friends, since that is the key for winning this game.
Fortnite is all about building cover and use it for your advantages, so I suggest that you practice in making quickk builds to cover yourself from enemy attacks. If you're playing on consoles/using gamepads, I also suggest that you use the Pro Builder config, since it makes you build faster than the other schemes.
