Ciudad Omega [Omega City]

The nuclear war destroyed everything. Now the only survivors remain alive in an underground bunker near some old military installations. Resources are scarce and someone must go outside for supplies. The Artificial Intelligence that controls the complex, which has called itself the Messiah, has selected you to go outside. However, the Artificial Intelligence has gone completely insane: If you haven't returned with the supplies within an hour, the bunker door won't open for you. And you will be left abroad at the mercy of the dangers of a radioactive world... As long as your lives last.
