These are all the locations:Northern side of the Chonker SpeedwayNortheastern corner of Greasy GroveThe JonesesNortheast of the Crackshot's CabinLonesome Watchpost, located west of Sleepy ShrubsBy Tiny Temple, southeast of The Daily BugleKeep in mind that UFOs have five seats, which means that an entire squad can be transported with them. However, their battery life is limited, so players will have to be careful and go easy on the Boost.As powerful as UFOs are, they only have 600 hit points. This means they can be taken down with less than one magazine of an assault rifle. They are also very big, which is why it's relatively easy to hit them from almost any distance.Fortnite UFO tips and tricks in Chapter 3 Season 3Fortnite Chapter 3 Season 3 has brought some new items that were not available during UFO's first appearance in Chapter 2 Season 7. Boulders are a new addition, and they can be deadly in combination with UFOs.As many players are aware, UFOs can pick up different objects and move them all over the map. Picking up boulders is almost a cheat code as it allows easy eliminations.🎄 Luna 💎@LunaFNCreateSo uhh boulders and ufos are incredibly broken #Fortnite9So uhh boulders and ufos are incredibly broken #Fortnite https://t.co/NOnvoJbhWeFurthermore, Epic Games has also added a new type of tree with Fortnite Chapter 3. These trees can fall on players and deal massive damage. Like boulders, UFOs are capable of picking up these trees and taking enemies down with them.Finally, if players decide to get into a UFO, it's always smart to bring a Rift-to-Go with the elf. If an enemy takes down one's vehicle, they can use the item to teleport to another location and avoid dying to fall damage.UFOs will stay in Fortnite Battle Royale for just a few days. They will most likely return to the vault on Monday around 8 AM Eastern Time.
