Unlocking Rebirth‘s Underground Prize Room: An Expert‘s Master Guide

As an avid Call of Duty player with over 9 days of playtime focused exclusively grinding out Rebirth Island matches, I was thrilled to tackle the latest Easter egg bunker hunt introduced this season. Through extensive trial and error across dozens of games, I successfully assembled the keycode and breached the hidden bunker below Headquarters to claim the exclusive Red Room Milano blueprint.

And I‘m here to provide fellow Operators with the most detailed walkthrough possible for unlocking this rewarding challenge based on my expertise. Let‘s get looting!

Locating The Key Clue Briefcases

The first major hurdle is tracking down one of the briefly spawning briefcases containing the key photos indicating code locations. Out of 13 potential fixed sites, only a single locked container appears per match.

I‘ve marked all the locations on this map along with key traits to help identify the landmarks:

These can be extremely tricky to pinpoint on such a small island, so I‘d recommend immediately jumping from the initial plane route towards site clusters like the Nova 6 Factory or between Bioweapons and Decon Zone. Clearing buildings floor by floor has helped me uncover 60% of my briefcase finds compared to 40% stumbled upon out in the open.

Pro Tip: Monitor the Rebirth LFG Discord channel where players will post the lobby number for an active briefcase they‘ve discovered to give you a precise target match.

Once you finally track down the unassuming briefcase, grab the trio of photos next to it depicting specific island locations. We‘ll use these to hunt down keypads tied to the bunker code digits…

Pinpointing The Keypad Code Sites

I cannot stress enough how critical it is to study and memorize the building or landmarks shown in these photos to identify where to extract the keypad code numbers.

For instance, one image might showcase an obscured section of the back warehouses and pipework around Nova 6:

This is signalling that the keypad is hidden on the crates or side door alcove of that specific building area. I‘ve investigated each photo perspective and matched them to precise map coordinates:

You must explore every inch of the photo site until you discover the stand-alone keypad device:

Activating it will display your first code digit (either 2 or 3 numbers). Follow this procedure for all three photos to compile the full bunker passkey.

Pro Tip: Photograph each code number displaying to keep digital references handy so you don‘t need to relocate keypads again if killed.

Now we‘re ready to assemble our island bunker code…

Constructing The Complete Code

At this point, you should have secured three numbers from the investigation of photo clues and activated keypads:

425  
146
27

We must now arrange them accordingly based on the access protocol discovered previously:

• 2 digit number placed in the middle
• Standalone 3 digit number goes at the end
• Remaining 3 digit number at the start

Piecing together based on these rules, our full Rebirth bunker keycode is:

42514627

This precise 8 digit sequence grants us access through the locked yellow bunker door!

Storming The Hidden Vault

By reviewing building layout blueprints, I‘ve confirmed the island bunker entrance point is on the ground floor of Headquarters towards the rear side:

Input the assembled passcode at the inconspicuous keypad hear to release the security hatch. Breach and clear, as rival Operators may be using this secluded spot as a temporary hideout.

Within awaits your just rewards…

The Red Room SMG blueprint for the Milano 821 rests on the table, providing a sick makeover for this speedy, high-accuracy weapon. Ensure your teammates also grab the blueprint to unlock in their own inventories!

A bonus Foresight killstreak pickup grants whole squad wallhacks for the next circle closure while the Specialist perk allows stacking all perks simultaneously for serious advantage.

There‘s also some cryptic emblems, documents, tablets and maps worth investigating for clues regarding Warzone lore and the island‘s research facilities shrouded in mystery…but that‘s better saved for dedicated detective Operators!

Mission Accomplished, Soldiers!

Congratulations on fighting through the trials to add this powerful SMG variant to your loadout options. Hopefully this guide has armed you with the tactical intel needed to achieve the same feat based on my extensive experience grinding for these secrets.

Let me know if this helped you finally snag that awesome Red Room blueprint in the comments! And stay tuned for more Rebirth Island bunker developments – I‘ll be on the case determining solutions for any new codes or rewards introduced.

Now get out there and claim what‘s yours, Operators!
