Since the failed attacks by hostile aliens, the nations of Earth have united. They worked together to build a defense network in space to protect themselves from danger.
In addition, the EXITUM-Program was opened to restore and preserve life even after complete destruction. Operation: OMEGA, is one of the components of this program.
In OMEGA, thousands of trained humans and civilians are placed in cryosleep in six bunkers on a protected and camouflaged island. As soon as the safety on the surface is guaranteed again, these people can be released again, who will then take care of the survival of mankind and animals.
