About
Stop The F is a first-person puzzle. Use a camera capable of capturing objects from reality into subspace and bringing them back. Use various filters that enhance the camera's performance. The project aims to recreate and reimagine F-stop, a canceled prequel to Valve’s Portal. While Stop The F draws direct inspiration from it, it is ultimately an original creation by an indie team, crafted with its own vision and identity.
