I examined the time lines of cata, and I would really like to be able to start from the breaking point. The hour 0 of the end of the world. Maybe under different roles, such as a soldier that is garrisoned in one of the military bases, or as a researcher that was working at a lab at the exact moment when the sub-space monsters broke through. You know, I would like to able to tell a story from it’s beginning, waking up in a shelter stresses me because I want to live in first person the struggle to safety while the world literally crumbles upon you. By my opinion this beginning would give cataclysm much more realism and a more consistent backstory, you could witness the military burning the corpses, executing the looters, the widespread anarchy, events such as a nuclear detonation, or simply turning on the radio to hear the desperate broadcasts of hopeless military units sent to die. You could act differently to every different situation, like a nearby town just got nuked, your first idea is to seek shelter from the fallout in the nearest evac. shelter or maybe a basement. This would also give cata much more life and interactivity between the player and the environment around him.
