Bomb

The dire threat of a cold war nuclear holocaust is slowly deescalating. Both East and West have agreed to back down. The world can breathe again. But then, without warning, a rouge agent has deserted and taken a thermonuclear warhead with him. We locate his headquarters deep underground. But he's a true doomsday believer and determined to see this through to the very end. The first agent we sent in is in trouble and communication has been lost. So we're sending you in. You're our last hope. The clock is ticking and the fate of humanity depends on your every move. Good Luck!
