With the advent of Season 4, two new exciting phenomena can be found around the Call of Duty: Warzone map. The first is the satellite uplink stations. Once these locations are secured, players will notice satellite debris crashing to the ground nearby which gives them rewards. The other is the mysterious Red Doors which play a key role in the Call of Duty: Black Ops Cold War campaign, but also serve to teleport players across the map if entered in Call of Duty: Warzone.

All of the Red Doors and the satellite uplink locations are not guaranteed to be in each match, but a helpful Redditor, covmike, has compiled a map that shows their possible locations. The Red Doors tend to be safer than the satellite uplink due to their out-of-the-way locations, and the fact that Warzone currently boasts a challenge tied to killing enemy players near a crashed satellite.

Luckily, players that complete the challenge of both securing a satellite uplink location and collecting the rewards from the debris will be given a satellite weapons charm as well as the Launch Time emblem. For the completionists in the crowd, it may be best to stick around and ambush enemy players in order to complete the challenge of killing 10 enemies near recently grounded debris or near an active uplink station.

Of course, since Season 4 only just released, and fans are still exploring all the new Warzone content, it's likely that there are plenty of locations still yet undiscovered or not added to the map. But, in general, due to the massive amount of possible locations for both the doors and the satellite uplink stations, players should still be able to complete the available challenges in a reasonable amount of time. A quick glance at the map reveals that it may be best to save the challenge hunting for matches that are centered around locations like Airport, Salt Mine, and Summit.

It's worth noting that players that travel through the Red Doors will be rewarded with a veritable treasure trove of loot including two legendary crates. While this reward may seem lackluster to some players who favor their loadout over other guns, the new additions to this season's loot including the C58 and the MG 82—which is already set to be nerfed—are among the best guns available in the game and have yet to be unlocked by many players.

Call of Duty: Warzone is available now on PC, PS4, PS5, Xbox One, and Xbox Series X.
