Warzone Underground Transit System explained

In a Season 3 teaser, players got their first glimpse at the underground mine cart system beneath Caldera. Following the Season 3 Reloaded update, this system will finally come into play. This new tool is an instant way to get around the map for quick rotations or outmaneuvering your opponents.

Once you access one of the 14 Underground Transit locations, you must simply enter a hatch and interact with the mine cart to travel to your new destination. Once you are close to the cart, “the destination name will appear on your screen – After a few seconds of travel time, you’ll instantly appear at your destination.”

Interestingly enough, players can use the light and audio clues to discern if there’s an ambush waiting for them at their next destination. A green light indicates that the coast is clear, while any other colored light hints at danger. Evidently, if the indicator is off with no information to deliver, you cannot travel to that destination.

The Underground Transit System‘s access points will be viewable through your in-game map. They will be indicated on the Tac Map and minimap by a silver “vault door” symbol.

Caldera’s Underground Transit System covers 14 different points of interest (POIs) across the map that are indicated by a silver vault door symbol on players’ tac maps. Here are all of the mine cart locations across Caldera:

Arsenal
Docks
Runway
Ruins
Mines
Peak
Beachhead
Lagoon
Airfield
Fields
Sub Pen
Power Plant
Capital
Resort

Almost every major POI across Caldera will have a mine cart access point. However, it is important to note that not all locations offer several destinations. Of the 14 access points, only Docks, Peak, Fields, Mines, Sub Pen, and Airfield offer multiple options when it comes to the destination.

How to Use the Warzone Underground Fast Travel System

With the Call of Duty: Warzone Classified Arms Reloaded update set to drop in the coming days, bringing with it Gulag Entry Tokens, Redeploy Extraction Tokens, a Serpentine Perk and more, perhaps the biggest news is that an Underground Transit System is coming to Caldera.

For those wondering what the underground mine tunnels are all about, here’s a breakdown of how to use the underground fast travel system in Call of Duty: Warzone Classified Arms Reloaded.

In Warzone Classified Arms Reloaded, the new Underground Transit System features 14 access points that are indicated on the Tac Map and minimap by a silver “vault door” symbol.

According to Activision, players who have kept a close eye around Caldera during Season 2 already know where seven of these access points are as they are the “hidden” Nebula 5 bunkers.

The door to the mine-cart hub room can be found right after dropping into each bunker. To travel via minecart to another hub area, players simply need to interact with the circular hatch and walk toward the cart. When doing so, the destination name will appear on-screen, as well as be interactive on the map.

Just be mindful of the lights around each hatch, any color besides a green one can indicate if an enemy is on the other side. If the indicator is off with gas going through the vents, then that means players cannot travel to that destination since it is out of the circle. After a few seconds of travel time, players will instantly appear at their destination.

How to travel in Warzone Underground Fast Travel System

To travel via mine cart to another hub area, simply interact with the circular hatch and walk toward the cart. When doing so, the destination name will appear on your screen — you can also check the map to see how it interacts. After a few seconds of travel time, you’ll instantly appear at your destination . . . Hopefully with no enemies waiting on the other side.

Those in the know — like you, after reading this section — can use light and audio clues to figure out if an enemy is on the other side, or if the circle collapse will soon engulf the destination. As with most situations, when there is a green light, it means it’s safe. Anything else can mean potential danger, and if the indicator is off with gas going through the vents, then that means you cannot travel to that destination.

Once inside, players can travel from point to point instantly without having to worry about traversing Caldera at ground level and face the fury of enemies looking to cut them down.

“To travel via mine cart to another hub area, simply interact with the circular hatch and walk toward the cart,” Activision said. “When doing so, the destination name will appear on your screen—you can also check the map to see how it interacts. After a few seconds of travel time, you’ll instantly appear at your destination…hopefully with no enemies waiting on the other side.”

Access points in Warzone Underground Fast Travel System

So, what about the other seven access points? Well, these are small hatches into the mine-cart hub area. You’ll find a map of the system there, with each hub location corresponding to a letter and number on the Tac Map. The blog post explains that the lower numbers indicate areas to the north – The hub near Arsenal is B1 – while higher numbers are hub areas near southern points of interest such as Resort.

Is The Warzone Underground Transit System Worth Using?

If the gas is closing in and you need a quick way to move to the next safe zone, using the Underground Transit System is a no-brainer. Even if you’re looking for a fast way to visit another area of Caldera, it makes sense to use the fast-travel system rather than using a vehicle that attracts the attention of all nearby opponents.

It’s unclear if the system will drastically change the pace of a typical Warzone underground system match but its arrival does open the door for even more ways to play.

Where is the underground place in Warzone?

West of Mines in D3: On top of the hill and near a small water pool just west of the large Mines road. Near Power Plant in E8: The hatch is inside a cave behind a waterfall near Power Plant. South of Docks in F1: In a dirt area very near three metal troop barracks.

How do you get into the bunker Warzone?

To access most bunkers, you’ll need a Red Access Card. These spawn at random and can be picked up organically – if rarely – as you loot, and while there’s no one particular way to guarantee finding one, keep an eye out for Legendary crates – they’re much more likely to spawn in one of those.

What are the yellow circles in Warzone Caldera?

As you jump into Warzone during season 2 and open your map, you’ll see multiple yellow circles drawn on your otherwise spotless atlas of the island. These indicate the location of several bunkers spread across the map, which you can of course fly towards and enter at your own risk.

What is an underground bunker?

A bunker is a defensive military fortification designed to protect people and valued materials from falling bombs, artillery, or other attacks. Bunkers are almost always underground, in contrast to blockhouses which are mostly above ground.
