About Signal
Signal is a third-person adventure set in a nuclear post-apocalyptic world shaped by quantum entanglement and time travel. You play as a father searching for his daughter, travelling between multiple worlds to uncover the story and find a way to survive.
You explore an open map, gather firearms and other resources, and investigate mission points. Along the way, you fight monsters and other enemies with modern guns, solve puzzles and collect clues. Conversations with post-apocalyptic survivors help you continue your search for the truth, while extreme life-or-death decisions shape the challenges you face.
