1. Killer Asteroid

65 Million Years ago, an asteroid impact caused a cascade of catastrophes that led to the downfall of the dinosaurs, but what would happen if the same size space rock struck near the same spot again? How would modern humans cope with a hailstorm of falling rocks and debris, mega tsunamis, out of control fires, blast-furnace temperatures, and a destroyed ozone layer? In the wake of worldwide destruction, who would survive...and who would perish?

3. Rogue Planet

There are twice as many rogue planets as stars in the galaxy. So what might happen if a ringed planet the size of Neptune were on a collision course with Earth? Within a period of just four hours, as people flee in panic, the gravity from the rogue planet would tear apart the Moon, stir up supersonic winds, trigger every earthquake fault and volcano, and finally pull the Earth to pieces.

4. Solar Storm

When Earth gets hit by a deadly Solar Storm--a massive chunk of the Sun--our planet's electrical system turns into a smoking ruin. How does modern civilization cope without power?

5. Nuclear War

World War 3 breaks out and a nuclear nightmare becomes reality as thousands of hydrogen bombs destroy the world's greatest cities. A deadly fallout of ash and debris creates a Nuclear Winter, plunging the planet into a sudden Ice Age. Crops fail worldwide and mass starvation drives humanity to the brink of extinction.

6. Gamma Ray Burst

The most powerful blast of cosmic radiation in the Universe is just seconds from slamming into Planet Earth. When a gamma ray burst from two colliding stars hits the atmosphere, the deadly radiation delivers agonizing death and immediately wipes out half the planet. On the other side of the Earth, the Americas face a slower death as ultraviolet radiation and starvation threaten to send the human race into extinction. How will the last remaining humans survive?

7. Mega Eruption

For the first time in human history, a volcanic hyper eruption blows through the surface of the Earth. Explosive shock waves tear apart buildings, molten rock slam into cities, and a deafening sound circles the globe. A bad day for Planet Earth gets worse as volcanic gas blocks out sunlight, food chains collapse, and epic famine threatens the very future of mankind.

8. Earth Out of Orbit

What if, for the first time in four and a half billion years, the Earth was pulled out of its orbit... sending our planet on a collision course into the Sun. Earth's deadly fall takes 65 days, triggering massive hurricanes, sandstorms and--with temperatures reaching over 200 degrees--a heat wave that kills every last person.

9. Alien Invasion

When rogue aliens launch a surprise attack on Earth, people are left dying in the streets, world governments are obliterated, cities are destroyed, and a deadly virus is unleashed. Can mankind survive or is this the end?

10. Deep Sea Disaster

Ocean currents control the climate around the world. When they suddenly stop, it unleashes an endless cascade of weather disasters, including blizzards, superstorms, wildfires, widespread drought, and rapid sea level rise. No place on earth is spared from this climate catastrophe that threatens to end human civilization.
