After months of teases and rumour, striking 3D puzzle game The Witness has finally landed in the App Store, for both iPhone and iPad. Likened to a modern-day Myst, the open world game sees players wake up on a strange, colorful island with no memory of who they are or how they got there. Only by exploring the vast island, discovering clues and completing curious puzzles can they hope to regain their memory and somehow find their way home. With dozens of locations to discover and more than 500 puzzles to solve, The Witness is a beautiful beast of a game, available now for $10/£10.
