How to get as many Alien Artifacts as possible in Fortnite Chapter 2 Season 7 (No Glitches)
The way to get the most Alien Artifacts for unlocking styles for Kymera is by getting Cosmic Chests. This technique allows you to farm 1 Cosmic Chest every 4 minutes. By doing it you will get to the max daily limit of 15 Alien Artifacts from Cosmic Chests in as little as 12 to 20 minutes.
You can get another 20 alien artifacts by picking up alien artifact drops around the Island. There are currently 5 on the map, worth 4 artifacts each, and more will be added each week.
You need 45 Alien Artifacts to unlock the final style for any given category of Kymera's customization options. To unlock all styles for Kymera you will need a grand total of 360 Alien Artifacts.
