From what I understand Fortnite Battle Royale can have up to one-hundred players, alone, in duos, or in squads of up to four players, attempting to be the last player or group alive by killing other players or evading them, while staying within a constantly shrinking safe zone to prevent taking lethal damage from being outside it. Players start with no real advantages, and must scramble around for armor and weapons to get the upper hand on their enemies. The game also adds the construction element from Fortnite - players can break down most objects in the game world to gather items they can use to build bases as part of their plan. Restricted time modes are cycled through the game that introduce experimental or unconventional gameplay but otherwise follow the battle royale "last player standing" goal. I can see something similar like this working in Doom, even Doom Etenal. But don't let this distract you from the fact that in 1998, The Undertaker threw Mankind off Hell In A Cell, and plummeted 16 ft through an announcer's table.
