Survival Diary is a zombie-themed first-person shooting survival game. Players will be in a zombie-filled post-apocalyptic world, using various weapons to fight against swarms of zombies. The game uses a day-based progression system where players face different numbers of zombies each day, requiring precise aiming and shooting to eliminate all incoming zombies to pass levels. Outside levels, players can upgrade low-tier weapons to high-tier weapons through a synthesis system, continuously improving combat power. The game uses first-person perspective to provide an immersive shooting experience, with low-poly 3D pixel art style creating a unique visual effect similar to Minecraft.
