This guide shows all Collectible Locations in Solaris of Destroy All Humans 2 Reprobed (DAH2 Remake). Includes all Prints (Posters), Artworks (Alien Artifacts), Jukebox Songs, Public Toilets, Human Cattle Hidden Hives.
Solaris is the 5th map in the game. Nothing is missable, you can continue in free roam after the story. For Collectibles it’s recommended to finish the story first because some items are in areas that require story progress to unlock. You can also make use of the proximity detector. You can select it from the world map by pressing 
to select a type to track and 
to activate/deactivate the tracker. When you are within roughly 10 meters of a collectible it will make a sound to help locate it.
