SSS Beast Apostle System and Survival Racing in Apocalypse.

When the aliens invaded earth, they didn’t come for its resources as many doomsayers had proclaimed throughout the years.

Instead, they came for fun.

They came, flattened earth’s biggest cities and turned the world into a planet-sized stadium for their civilization.

The sport?

Survival Racing.

Ferocious alien beasts were unleashed upon the ruins of the world along with thousands of alien death-row fugitives who were only told one thing: Kill the humans, survive the year and regain your freedom.

Elliot was a survivor. He died right before he entered the final 15 days of the Games.

But as his consciousness began to slip away, a metallic voice rang out within his soul.

Mission failed.

SCREEE!!

He took the corner at record speed like a professional racer and then floored the pedal to the metal once more!
