"Thus shall you think of this fleeting world:
A star at dawn, a bubble in a stream,
A flash of lightning in a summer cloud,
A flickering lamp, a phantom, and a dream"
The Witness is a puzzle adventure game, experienced in the first-person view. The player, as an unnamed character, finds himself on an island with numerous structures and natural formation. The island is divided into ten sections arranged around a mountain that represents the ultimate goal for the player. Within each section, the player will encounter numerous puzzles, and once the player has completed all puzzles in a section, a gold turret will emerge from around that section and shine a light towards the mountain. The player needs to complete seven of the ten section sections to be able to access the puzzles within the mountain and complete the game.
