The trials of divinity

Overnight, 390 people aged 18 disappeared from the world — two from each country. However, they were soon found on a battle royale TV show. The premise was simple: death meant elimination, and the winner would receive 10 billion USD, or the equivalent. Once a contestant died, they would respawn in the real world at the end of the game. However, this was no simple game. The contestants possessed abilities beyond ordinary humans, perhaps even godlike.
