#ONTO VS ONE TO ONE HOW TO#
Learning how to build around your enemies is a skill that you can only perfect by playing against other players. One-vs-ones tend to evolve into box fights quickly, meaning you can find yourself placing walls more often than shooting. Having a decent aim will always be needed to finish off your enemy, but it won’t do the trick on its own if you don’t combine it with a decent level of building. Multiple factors are included in the equation of each one-vs-one, however. Building up your muscle memory through practicing Fortnite will allow you to react in similar moments without thinking for a second, allowing you to catch your enemies off-guard. Though one-vs-one scenarios may cause nerves to act up, you can still keep your cool by preparing for the moment. Your demise can eliminate your squad completely, so the pressure will be on. Regardless of the game mode you prefer playing in Fortnite, you’ll find yourself in countless one-vs-one situations where you’ll need to pull through to secure a Victory Royale.
