Set up surveillance around the island.

Many quests you’ll come across in Fortnite are scavenger hunts that send you all around the vast island. One of the trickier ones you’ll encounter asks you to set up scanners to form a warning perimeter.

This is a tough task to get done since there are quite a few spots you need to visit and a lot of traveling you must do to find them. Although this one can be a bit difficult to navigate, the XP you get for finishing it is worth the effort, so here’s how to set up scanners to form a warning perimeter in Fortnite.

To set up scanners to form a warning perimeter during The Fall of Supernova Academy quests, you need to visit five locations around the island and place a scanner at each one. All of the spots you need to visit are situated around the center of the island in a circular formation, so traveling around to all of them takes quite a bit of time.

It’s fairly tough to get this task done in just one round, even if you start with it right away. Luckily, your progress is saved between rounds, so you can work on this quest as many times as it takes to travel to all of the required locations.

At each location, look for the white diamond icon and a sparkling outline of a scanner to find the right spot to set the equipment up. Approach this spot and interact with it to place a scanner, then set out to the next spot to progress through this quest. The toughest part about this task is finding the right spots to place the scanners since they’re all fairly random and very spread out across the map.

There are five spots you need to visit around the island to set up scanners to form a warning perimeter. You can visit these locations in any order, but all five must have a scanner placed before you can progress to the next quest in this series. All of the locations you need to venture to are as follows.

  • Near the north end of Shiny Shafts.
  • Northeast of Canyon Crossing near the parking lot.
  • Northeast of Demon’s Domain on a hill near the flower fields.
  • North of Shining Span and a BURD To Go gas station near some geysers.
  • Near the road northwest of Supernova Academy.

If you’re hoping to get this task done in just one match, heading to one of these five spots straight from the battle bus is crucial. After placing your first scanner, work your way around the island in a circle, hitting each location along the way, to get all five scanners down as fast as possible. It’s a good idea to grab a car or a useful traversal item like the Surf Cube or Bass Boost to make getting around quickly an easier task.

There are plenty of other tasks to tackle around the island once you’re done with this one. If you’re not sure what to do next, you might want to become Superman, hit hero practice targets at different hero training outposts, and assemble surveillance gear at Demon’s Domain.
