The end of season 3 of Warzone and Modern Warfare is around three weeks away. With Season 3 in full swing, leakers found elements in the files that would lead to believe that the map will see a radical change. Infinity Ward has already discussed the potential of large-scale in-game events taking place in Warzone, in a similar fashion to Fortnite..
The map will either undergo a partial change, or it will be a brand-new map. In the game files, the leakers found a Warzone map called Urzikstan. We can think of a scheme similar to Apex Legends, with rotations in the maps or a complete rework of the map as on Fortnite. A lot of scenarios are possible, but at the minute, these are all rumours as to what could be happening in season four.
Speculation revolves around a nuclear attack that could destroy the map we already know is floating on Reddit. This could make the new map likely to be called "Urzikstan" appear. However, nothing has been validated by Activision or Infinity Ward so take this information with a pinch of salt until there is more concrete evidence!
