It goes like this: Everyone between the ages of 7-21 are transported into another planet by a group of ASBs. The main intention of the transportation is to create the perfect Social Darwinist society. The planet the transported children end up is a planet where giant monsters, otherworldy creatures and lifeforms evolved in bizarre, frightening and brutal ways. The planet is surrounded by dangerous climate and hazardous biomes. The planet is filled with remnants of modern and ancient ruins, as well with wrecks of ships, vehicles and other items. The planet has strange portals called Tears, which carries in objects, valuables and other stuff into the world. How should I prevent this ASB scenario from being a Mass Death Scenario?
