After you finish a day (when you are done killing zombies) a To Do list comes up and shows that you have 12 hours.. you divide those 12 hours up. Depending on what you need to do. If you need to repair the wall, find weapons, find survivors. Click accept then it automatically does it and shows you the results right after. It shows you the percentage of the wall that was repairs, how many survivors if any were found, and how many weapons and what type were found if any. Then the next day starts. You don't actually go out looking for survivors or guns in the game.
