Building in Offence
Ramp Rush is one of the most known techniques in Fortnite. Building it is not hard, but it takes some time to learn. Ramps by itself are pretty straightforward to build - place stairs on top of each other and you are done. These ramps are very weak and can be destroyed very quickly. Fortifying ramps is the tough part, but it will allow your ramps to withstand surprising amounts of damage. To fortify it - build walls behind and around ramp. Behinds walls are the most important ones, because they protect stairs. Around walls will protect you.
There are a few common building techniques that are surprisingly effective. One of them we call Maze Rush. It's main purpose to get close to your enemy and it's not very hard to execute - move chaotically and place walls on your way. Walls will act as shields and they will provide both cover and distraction and will allow you to minimise distance between yourself and the enemy. Don't forget to keep track of your enemy, and beware of flanks.
