Slide an Ice Puck Over 150m Challenge
One of the Fortnite Battle Royale Week 6 Season 7 Challenges requires you to "Slide an Ice Puck over 150m in a Single Throw". To unlock the Ice Puck, you need to first reach tier 28 on the battle pass.
Equip the Ice Puck and then head to the mountain by Polar Peak. Throw the Ice Puck off the mountain and onto the ice lake below. You should easily get 150m thats required for the challenge this way.
