The 24 Hours challenge. You have 24 hours on easymode and then uberhard zombies kick in and always know where you are. I know at the time that they would just find me, so I stockpiled food, drink, amusement, booze, pills, clothes and medical supplies. I didn't find any firearm or good weapons, and the best I got is a shovel. On the 13-hour mark I return home and sleep for 8 hours. An hour before the death mode starts, I eat to full and hide in the starter house that I covered the windows, and barricaded three doors in. I wait up, and hear a lot zombie noise outside. Then suddenly, I can hear the bastards whacking on my doors from my room on the second floor. Knowing it was the time to die, I eat a pack of painkiller pills, and gob down a package of calming medicine. I drink all my booze (2xbottle of white wine, a bottle of red wine, and 1/2 of a bottle of whiskey), make a molotov, open the door to my room, throw it, and die the deat hof a warrior. I caught on fire, and the twenty-ish zombies that came in were lit with my corpse. I killed 11 before dying, but I think those were mostly from before kill-mode happened. Then suddenly, my hous caught on fire. My corpse turned into ashes, and those monsters dying in the purifying flames were the best thing I watched in there. They tried to escape but to no avail. They almost all died, and my house was a wreck. My trusty shovel (and the rest of my inventory) was all that remained of my earthly possesions.
