Call of Duty: Warzoneplayers have finally seen the game integrated withCall of Duty: Black Ops Cold War, and a new map has been released alongside that integration. The highly anticipated Rebirth Island map is now playable inCall of Duty: Warzone, and the map includes a complex new Easter egg for players to complete.

The first team to complete the Easter egg was led by YouTuber Geeky Pastimes, and it sees players scouringthe Rebirth Island mapfor a briefcase and codes to open a large yellow door. Once opened, players get access to the exclusive “Red Room” blueprint for the Milano SMG, with the stylish look coming alongside perks such as foresight and a gas mask. Players should be warned that the Easter egg will be a bit challenging, however, as it relies entirely on RNG.

Step 1: Find The Briefcase

Geeky Pastimes and his team of Easter egg hunters spent eight hours solving the “yellow door” quest, with the team taking so long due to the randomization of the briefcase’s spawn point. So far, the dedicated group ofCall of Duty: Warzonefanshave supposedly found 6 of the 8 locations for the briefcase, highlighting them on the map above. Players will need to check each of these locations, hoping that the briefcase has spawned into their game.

Once found and opened, the briefcase will give players hints about the next step, which is once again going to be randomized.

Step 2: Secure The Codes

Accessing the bunker of Rebirth Island is far more difficult than getting intoCall of Duty: Warzone’s airport shelter, as the Verdansk location does not require the completion of a complex code puzzle. For players to complete the code to the door, they will need to look at the three locations shown in the photos of the opened briefcase. Each location will point to a random area on the map where the code can be found, such as a cement mixer in the construction area. The marked item will feature a piece of the code, with players needing all three pieces of the code to complete the 8-digit number.

Players should pay specific attention to the hyphens after each set of numbers, as they indicate its place in the sequence. The code piece with two numbers will always go in the middle. An example would see the code pieces 213-, -37, and -568 making the code 21337568.

Step 3: Claim The Reward

Once players have been rewarded by good RNG and successfully assembled their code, they will need to go to the Headquarters Command Center to open the large yellow door. Entering the code in the keypad to the right of the door, players can then walk in, claiming the special blueprint for their SMG from a table. Entirely unique from the blueprints seen inthe Season 1 battle pass, the special Milano design is a great way for players to show off their Easter egg completion.

While the Easter egg took Geeky Pastimes’ group “eight hours” to complete, having a guide should make the process a bit easier for players. However, with not all briefcase locations being discovered and the process completely relying on RNG,Call of Duty: Warzoneplayers may have better luck getting theirdisabled Double XP tokensto work again.
