With the Season 3 Reloaded update, a new fast travel system will be implemented in CoD: Warzone. The underground system plays a central role in this. In Caldera, you can teleport from one location to the next using mine carts.
With the fast travel system, it is possible for the players:inside to quickly get to another point on the map. This is very similar to the red doors that were added in Verdansk with Season 5. However, this time there will be an underground system with mine carts that stretch across the entire map and serve as entry or exit points for players.
There will be a total of 14 entry points in Caldera. These are hatches that have been equipped with a ladder to gain access to the underground. The entrances are marked on the map with a silver vault door symbol. This allows all players to know the location at all times.

On reaching the underground, CoD fans only have to approach the mine cart. The name of the destination is then displayed on the screen and after a few seconds the players travel there. However, it is possible that enemies are waiting for you at the other end. Therefore, with the fast travel system, there is a risk of being eliminated by an enemy in the next moment.
