Ember

Intro The world is ending. The sun gave out, and now it's cold and dark. People now live in underground labs, which are like small towns. People have now evolved into hybrids and need to wear snowsuits with powerful heater systems to keep them from freezing outside. They use a new type of gun called Sun Flare that can make a small sunlike orb for 15 minutes to be able to see in the area. They all need to wear night goggles. There are some humans still left, but they are super rare now. You were there the day the sun blew up, but your mom, who was a scientist, threw you into a cryopod to save you. You were frozen for 200 years and are now waking up in the new dark world, where there's endless war for food and territory from other people that survived in different bunkers.
