It does feel like every online game out there one to have some sort of Battle Royale mode but according to id Software, the developer behind games like Quake, this has been around for some time now.
According to Tim Willits, Quake did have a mode made by the community where players have to fight to be the last player alive. That mode only supported four players but the idea is there.
When asked if they plan to offer some sort of battle royale game in the future, he added that games like this take a long time to develop and that the craze for battle royale game might have died down when they finally have something ready.
He added that copy a popular game mode will always mean that you are late so they have to be careful when they pick something trendy to work on.
