This achievement is for collecting 25 Alien Energy Cells and 25 Alien Plants. You will need to upgrade your house a few times before this Alien Debris becomes available to collect.

Alien Energy Cells

The Alien Energy Cells can only be collected between dusk and dawn, however they give off a good glow which makes them easy to spot. They also only show on your map as Alient Debris at night.

Here is a video by jidenshaotoko, showing the location of all 25 which helped me find the last one I was missing (number 19 in the video).




Alien Plants

The Alien Plants can only be collected when there is precipitation. They also only show on your map as Alien Debris when it is raining or snowing. I recommend you don't use fast travel as that often stops the rain.

Here is another video by jidenshaotoko, showing the location of all 25 Alien Plants (although this time I found them all myself).



Be sure to give them a like if you find their videos helpful.

And for those that prefer a map method:

only issue i've found is all the alien ones are the same marker, so if its not night AND raining, its hard to tell which from which.

i know i managed to have most of the boards and alien stuff get discovered as i was driving around getting the roads, even if my house wasnt upgraded enough to start collecting them, so i just needed the location of one or two of each.

For this to unlock you need to find and smash all the Alien Cells AND all the Alien Plants (these can be found in the rain straight after unlocking the football pitch for your house).

EDIT: Just heard on Horizon Pulse from the DJ that the second lot can be obtained in rain AND snow so if you’re having a hard time finding them, wait until Winter maybe?
