Infinity Ward has released the big new Season 6 update for Call of Duty: Warzone, bringing with it a number of important changes to the battle royale. Most of the Warzone Season 6 changes were detailed in the patch notes, but like always, Infinity Ward also made some changes that it left for fans to discover on their own.

Here are all the secret changes in Call of Duty: Warzone Season 6.

Air Traffic Control Tower

This secret change will likely be missed by most fans, but Call of Duty: Warzone actually changed up the appearance of the Air Traffic Control Tower at the Verdansk Airport. After going up the elevator shafts, players will discover that the interior of the Air Traffic Control Tower building has been cleaned up quite a bit. It's less cluttered, and players can move more freely behind the staircase. It's unclear why exactly this change was made, but Infinity Ward has been known to make subtle tweaks to the Warzone map not unlike this in the past.

Foresight Killstreak

Arguably the biggest secret change to Warzone is the addition of the Foresight killstreak. The Foresight killstreak is an extremely rare killstreak that appears to only spawn in the Warzone bunkers. The reason it's so rare is because it gives Warzone players a significant advantage, allowing them to see the locations of all the circles on the map in advance. This allows players to position themselves at the final circle well ahead of other teams, and gives them a far greater shot at winning the match. Some fans have already voiced concern that the Foresight killstreak might be a little on the overpowered side, so it's possible Infinity Ward will tweak it, but that remains to be seen.

Ghost Girl

Infinity Ward has confirmed that a Warzone Halloween event is in the works for October 20. What exactly it will entail remains to be seen, but the running theory is that it will introduce a Warzone Zombies limited-time mode. Backing up that theory is ghostly girl laughter that has been heard all over the Verdansk battle royale map, particularly in the woods near Lumber and Stadium. Some fans have theorized that the ghost girl is Samantha from the old Zombies storyline, but it could just be a generic ghost. Fans will likely have to wait until a little bit later in the month to get their answers.

Self-Revive and Specialist

The Foresight killstreak wasn't the only new item that Infinity Ward sneakily added to the Warzone battle royale in the new update. It also added some other rare items that, like the Foresight killstreak, should give players a big advantage on the battlefield. The first is a self-revive kit, which gives players an instant self-revive without forcing them to pay $4,500 for it at a Buy Station. The other item is the Specialist Bonus item, which gives players all the perks.

Subway Station Easter Egg

When Infinity Ward opened Stadium on the Warzone battle royale map, it commemorated the occasion with an elaborate easter egg fans could complete in exchange for a new weapon blueprint. Now the same has been done with the Subway Station, which opened as part of Season 6 to allow Warzone players to fast-travel across the battle royale map. Those that manage to complete the Subway Station Easter Egg will get their hands on the Firebrand blueprint, which is a special version of the Bruen MK9 LMG.

And while most of the secret Season 6 changes apply to Warzone, Infinity Ward has made at least one secret change to Modern Warfare as well. The Modern Warfare Gunfight map Station has an Easter Egg of its own to complete, and doing so will allow players to summon a giant teddy bear with glowing red eyes. Luckily, an airstrike is called in to destroy the bear before it can wreak any damage on humanity.

Train Spawn

A rather small, but still noticeable, change that was made to Call of Duty: Warzone Season 6 has to do with the train that runs across the battle royale map. The train was added to Call of Duty: Warzone with Season 5, and it has since become a popular landing spot thanks to the fact that it usually has high-tier loot. However, with Season 6, landing on the Warzone train may be a little more complicated, as it now doesn't spawn in the same exact part of the map as it did in Season 5. Players will want to keep this in mind when deciding where to land at the beginning of any given Warzone match.

Call of Duty: Warzone is out now for PC, PS4, and Xbox One.
