Rocket jumping is a simple yet strategic mechanic that can give the player an height advantage. It allows for an easy escape out of tough situations and can be used to get a better view on other players.

Point at the ground and jump right before shooting a rocket (left click). You don't have to jump prier to shooting, but it does help with getting higher elevation.

Do keep in mind that the splash damage from your own rocket will deal 5 damage to yourself. Other than the small damage dealt, it can be a good trade depending on the situation.
