a quiet place

*as you walk on the sand path you made to quiet your footsteps to avoid the creatures a gunshot rings out and the screeching and wooshes of hundreds of them sound* about: 105 days ago meteors from a planet with creatures fell down on earth causing death and panic and destruction nearly half the population being slaughtered tyhe creatures are deprived from vision but there hearing is very well so too loud sounds can hurt them and stun them be you choose everything they are very fast also...be realistic*
