[ WP ] After a nuclear war the survivors were sent underground to survive the radiation . Years later a kid escapes to the overworld . You are that kid . What does he find ?

His heart was pounding in his throat, his palms damp and his shirt clinging tightly to the skin, moist with the efforts of his exertion. He cast a glance over his shoulder to check the tunnel was still empty. 
 
 Good. 
 
 In the distance he could hear footsteps approaching however, so his time was brief. Grasping the cool metal handles he heaved, gritting his teeth as he did so. Slowly the rusted joints began to creak and turn, the very air itself seeming to grind against itself as the handle continued to move. 
 
 Then a thin slice of bright yellow light cut through the dust, illuminating the particles that danced through the air. But it was a light much purer than that to which he was accustomed. Intense, almost blinding. 
 
 With the light came the wind. A faint whistle of warm airflow that swirled around him as the door opened. As the hatch opened fully, the light hit him full in the face. He could feel his skin rippling in the heat, the breeze caressing his hair sending it into a delicate tumble down his face. 
 
 An eternity seemed to pass to him as time drew to a close, this moment could last forever. 
 
 But a blaring alarm cut through the peace, shattering the fragile silence he had tried so hard to enjoy. 
 
 `` Hatch B3 open,'' a synthesised voice announced, `` Hatch B3 open.'' 
 
 A hand gripped the back of his shirt, pulling him back inside. Twisting himself abruptly, he felt the seams tear and pull through the fingers that grasped at it and he started to run, his chest now bare as the light warmed that too. 
 
 Slowly, as his eyes became accustomed to his new surroundings, several objects came into focus. He turned around, looking at the hatch he had just escaped from. 
 
 *B3*, read the lettering above it. Thick red blocks that marked its designation. Further away, more hatches. Arranged into neat rows. In one direction he could see them counting up. In the other they stretched into the distance, all identical save for the lettering above them. Hundreds upon hundreds of equal hatches. All of which had just opened. Children his age, some boys, some girls, stood blinking into the new light. They caught sight of each other and he smiled at the boy nearest to him. 
 
 As the boy smiled back, a sharp crack rang out, echoing through the sky. The boy's face erupted outwards in a fountain of red, his eyes rolling backwards into his skull and his legs folding underneath him. From further away, more crack began to build in crescendo, and he turned to see a man he did n't recognise holding some sort of black metal tube. 
 
 He ran. He ran until his limbs screamed at him and his lungs burned, the fire rising up his throat. 
 
 Eventually the noises began to vanish as he continued to run across the burning sand.
