The document provides details for a proposed first-person zombie survival horror game. The game would be set in a post-apocalyptic version of London and the English countryside. Players would control Jason Blake, a 27-year old working-class survivor, as he searches for his family. Gameplay would involve scavenging for weapons and supplies, encountering other survivors and hostile infected humans, and exploring the open-world environment. Key elements include the use of photorealistic graphics to create an immersive atmosphere, a focus on themes of isolation and declining mental state, and character customization through experience points.
