You wake up alone on an unknown island full of challenging and surprising puzzles. You can't remember who you are or what brings you here, but there's one thing you can do: explore the island in the hopes of discovering some clues that will help you regain your memory and somehow find your way home. Witness is an open-world single-player game with tons of locations to explore and over 500 puzzles to solve. This game is an expression of respect for the player's intelligence and their precious time. There are no fillers in it. Each of the puzzles brings something new to the gameplay. It is therefore a game full of ideas.
