Olympus: The Agency

Hundreds of years in the future, a government-backed black ops group clones people who died in the past to form a group of deniable assets to perform missions. Stripped of names, these people are granted codes to live by instead. Agent Zeus leads this group of dead people to survive in a universe they do not understand. But as time goes on, they must make difficult decisions just to get to the next peril.
Sometimes death is preferred.
