From PCGamesN: “Want to know where Lara Croft is in Fortnite? A new Fortnite weapon was added to the game recently: the grappler bow. While this exotic bow isnt very helpful for eliminating players, it is very handy for getting to high places as a fully charged shot will fling you across small gaps or on top of buildings. In many ways its similar to the grappling gun from past updates, only you need to charge up a shot.”
