The unique factions provided by this mode additionally help create the new world ravaged by the nuclear apocalypse and provide interesting gameplay styles. What makes this scenario so great is in how it completely changes how one plays Civilization 6, with violence being the only way to secure victory and fragility being constant threat. The game keeps going until there is one player left standing in order to get a spaceship to get off the planet. The Red Death that the scenario is named after is a radioactive mass that is slowly enveloping the world that will damage all units inside it, as well as deal more damage as the game progresses. It takes place during the post-apocalypse with players controlling unique civilizations not available in any other game modes.
Red Death is a battle royale styled scenario that was added for free in the September 2019 update for Civilization 6.
