All stars | Messengers and Stars The Talos Principle Guide

A star.

Stars can be found behind closed doors, hidden passages, in places hard to get to. Often they are placed beyond the levels with the sigils, but sometimes you must do specific actions in the level to get the star that is hidden outside it. Getting all the stars requires much effort, but it is required to unlock the last ending.

Additional levels with stars

An example of additional level.

Additional levels with stars are unlocked for every ten stars gathered. Before entering the bonus level you must solve a puzzle. The solution can be found in another chapter of this guide. In each of three main worlds there is one additional world with three levels, there you can find gray sigils. Gray sigils are needed to unlock the sixth floor of the tower. Each bonus world has a board with a digit of the code required to unlock the sixth floor of the tower. When you will get all gray sigils, you can open the highest floor of the tower. More information can be found in the chapter about the tower.
