How to deploy scanners in the alien biome in Fortnite explained
When you visit these biomes, you'll easily be able to find the scanner roughly at its centre and all you have to do is activate it.
In the terms of the central biome, the scanner location is a little different, being located on its left-hand side and close to the fork of the river, but there is still one here for you to activate.
It doesn't matter which alien biomes you visit nor the order in which you do so - you simply have to visit two and activate two scanners to complete this legendary quest.
