It looks like battle royale gaming style is conquering more and more games. Civilization 6 is the latest to offer a battle royale of sorts in a new free mode called "Red Death."
The "battle royale" represents a fixed number of players that will fight each other until only one player remains alive. As the match passes, the you must retreat to a "safe" zone as a "storm" or in this case "red death" will kill you. Civilization 6 battle royale mode will have up to 12 players in a match, and will work as a usual battle royale in which the last man standing wins. You can play with less than 12 players or even against A.I. if you're more of the introverted type.
"Nukes" we're also added to this mode, and you can use them late game. To be able to launch a nuke, you must collect "uranium," research "Nuclear Fission," and finish the "Manhattan Project"....
