It's Week 10 and there's a new challenge that has you looking for signs in various locations.
For this challenge, you're looking for posters that change from a red, triangular warning sign to an image of a public service announcement in three Named Locations.
There are several of these posters in each area, so if standing near one doesn't work, there will be several others nearby.
Fortnite: Visit different public service announcements signs in Neo Tilted, Pressure Plant or Mega Mall
For this to work, you'll need to stand near the signs and wait a few moments as they switch between the warning sign and the more motivational public service announcement.
At the Pressure Plant, land near the robot factory. There are at least three public service announcement posters dotted around the base of the giant robot, so here's what you're looking for.
At the Mega Mall, you'll find them near the entrances to the mall plus in the car park.
In Neo Tilted, it would be best to land in the Southeast of the area, and have look around the outside of buildings to find them.
