The Sun Also Rises

Hide from the sun, run from the night. The atmosphere has been gone for sometime. The sun has scorched most things on earth and makes it near impossible to survive on the surface. You, your friends, and your family, seek shelter in an underground bunker. Everything is perfect until the food rations start running low and your friend disappears. You set forth on a journey to find your missing friend and find enough food to keep the shelter alive.
