Stars are collectible items in The Talos Principle.

There are a total of 30 stars scattered through the different areas. Signposts indicate the number of stars available in each of the basic areas (A-1, A-2, etc.), but there are also some stars in the hubs.

Many stars require going outside of the ordinary area bounds, taking puzzle items outside of their original puzzles, or connecting lasers to components outside of basic puzzles.

Collecting every star is a requirement for reaching the messenger ending.

Road to Gehenna

There are 16 total stars in the DLC, four in each of the four worlds. An additional world can be accessed after collecting at least 10 of these stars.
