The Port-A-Fort is the most recent item that has been added to Fortnite and has helped players to defend themselves in tricky situations and gain the higher ground.
The Port-A-Fort only comes in the Epic rarity and when players throw this item, it creates a metal structure that gets built immediately upon impact.
