In the past, new items were introduced to Fortnite through content updates. It was almost certain that something new would be added to the game every two weeks. Over time, Epic has withdrawn from this form and at this point, items are introduced with the normal updates.
Leakers say developers are working on a fire extinguisher at the moment. So far, the opinions are rather average, but it must be remembered that it is not yet known how the fire extinguisher will work.
A new item is coming to Fortnite
There is a good chance that the fire extinguisher will be added in Update 14.50. However, this information is not confirmed and should not be treated as such.
The description suggests that the fire extinguisher will extinguish the fire as standard, there is no surprise here. However, if it is to be used only for this purpose, it is unlikely to be used very often.
We know from people searching the files that so far there are no hints about possible injuries, special effects or restrictions related to the game modes.
