Call of Duty: Black Ops 7's Season 2 is here, and while it does bring heaps of new content to explore, Call of Duty: Warzone also receives a sizable update. Though the game has gotten a bunch of new weapons for players to grind for and unlock, the biggest update has to be the arrival of Winter Rebirth Island, which has covered the iconic map in snow.

Winter Rebirth Island is not only a neat aesthetic change, as new points of interest have been added, some of which have a bunch of new secrets for players to uncover. This is the case with the game's secret bunkers, which allow players to open the map's old Gulag and get a free weapon blueprint. Here is how to open the Old Gulag on Rebirth Island in Warzone.

Call of Duty: Warzone has received new Camos for Season 2, which can be unlocked by racking up consecutive wins. Here's the intel.

Step #1: Open the Outpost Bunker & Grab the Computer SSD

For the first step, you will need to open the bunker at the unnamed POI, the Outpost. This bunker can be found on the south side of the Living Quarters. In order to open it, you will either need to throw a Molotov or a Thermite onto the red button on the right side of the bunker door. Doing so will melt the surrounding ice, allowing you to interact with the button to open the bunker.

From here, head to the back left of the bunker, and inside, you should find a Computer SSD. Loot this item and proceed to the next step.

For the next step, you will also need another Molotov or Thermite. To get one, loot around or equip it to your loadouts and grab it from a Loadout Drop. Also, try using a Munitions or Utility Box to get two right from the get-go.

Step #2: Open the Turbine Bunker & Acquire the Code

For the next step, proceed to the Turbine POI and locate the bunker in the western portion of the location. Here, just as before, use a Thermite or a Molotov to melt the ice around the button to the left of the door, then interact with it to open the bunker.

In this bunker, you will find a terminal. If you have the Computer SSD equipped, interact with the terminal. Doing so will generate a binary code. Take note of this code and proceed to the next step.

Call of Duty: Warzone introduces the hardest Easter Egg yet with the Bloom Moon Ritual on Haven's Hollow. Here is how to complete it fast.

Step #3: Head to the Prison Tunnel & Open the Gulag

For the next step, you will need to open the Gulag. To do so, proceed to the tunnel leading underneath the Prison. This can be accessed by a staircase or via the tunnel entrance towards the northwest side of the Prison (marked by a Weapon Trade Station). At the very end of the tunnel, you will find a door with a keypad terminal.

Here, players will need to activate a sequence to input the binary code. To do so, players will need to match the light sequence with the code they received, turning the light on by pressing the interact button while the light is on if the digit is 1, or leaving it entirely if the digit is 0. In our case, the code was 10011, so we had to turn the first light and the last two lights in the sequence on.

Completing the sequence correctly will successfully open the Gulag, rewarding players with the Past Secrets Animated Emblem.

Step #4: Engage or Disengage the Switches in the Gulag According to the Notes

To complete the final step, you will need to engage or disengage a series of switches according to the notes provided next to each switch. To do this, interact with the keypad towards the locked safe at the far end of the Gulag, then go to each switch in the correct order, interacting with each note to check if it needs to be engaged or disengaged.

If the note says engaged, interact with the switch to engage it. If the note says disengage, leave it alone and head to the next one. However, the catch is that you only have a limited time to interact with each switch, and the switches themselves are only interactable while they have the push icon visible (hand icon).

The best method to complete this quickly is to have one player at the terminal to activate it, while the other players head to the first switch. Doing so gives you enough time to view the notes beforehand, saving time. For the correct order, view the provided map above, or check the provided video for more guidance.
