As we can see in the trailer of the Battle Pass in Chapter 2 of Fortnite, it is possible to fight on the water with motorboats. You can climb to four on the outboard to conduct high-speed chases on the various water points available on the new battle royale map. One can drive the boat while the others can shoot up the enemies.
These new vehicles can be found on beaches everywhere on the map. As mentioned above, you have the possibility of being alone or with several people in these boats, but in any case you will have the possibility to use the missiles equipped on board — even while driving.
Another important point to note is that motorboats can also be used on land, where they are slower. For the rest, it's pretty basic since the vehicle has a boost that can be used once loaded.
