Complete guide to obtaining and upgrading the Ray Gun Mk 2 in Black Ops 6 Zombies with expert strategies

Introduction to the Ray Gun Mk 2

The Ray Gun Mk 2 represents one of the most coveted Wonder Weapons available in Call of Duty: Black Ops 6 Zombies, offering devastating firepower that can turn the tide of any match. Located exclusively within the Shattered Veil mansion, this upgraded version surpasses its predecessor with enhanced damage output and specialized elemental modifications.

Unlike conventional weapons obtained through Mystery Box luck, the Ray Gun Mk 2 requires completing a multi-step Easter egg quest that tests both your problem-solving skills and combat proficiency. This intentional design ensures that only dedicated players who understand the map’s layout and mechanics can wield this powerful armament.

The strategic value of obtaining this weapon extends beyond raw damage—it serves as a cornerstone for completing Shattered Veil’s main questline and provides access to three specialized variants, each tailored for different combat scenarios and playstyles.

Step-by-Step Acquisition Process

Begin your pursuit by reaching at least Round 10, which activates the spawn conditions for the specialized Lab Technician Zombie. This unique enemy appears randomly in either the Mainframe Chamber or Security Overlook areas—two locations that require previous map progression to access efficiently.

  • Eliminate the Lab Technician Zombie to secure the essential Floppy Disk item. Pro tip: Use high-damage weapons or traps to dispatch this enemy quickly, as it will attempt to flee upon taking damage.
  • Proceed to the East Foyer and insert the Floppy Disk into the fax machine, which will generate a document revealing one of four possible codes: MOTH, YETI, CRAB, or WORM. Memorize this code immediately to streamline subsequent steps.
  • Navigate to the Nursery and examine the blackboard, which displays a randomly generated letter grouping system each game. The key to deciphering your code lies in counting how many letters appear in each grouping cluster surrounding your specific code letters.
    • For example, with YETI: Y in a five-letter group becomes 5
    • E appearing in a four-letter cluster translates to 4
    • T found within an eight-letter arrangement gives you 8
    • I located in a two-letter pair provides the final digit 2
  • Input your resulting four-digit code (5-4-8-2 in our example) using the keypad adjacent to the downstairs Doppelghast. This action will summon the spectral enemy that must be eliminated to obtain the severed arm.
  • Transport the severed arm to the DNA scanner situated in the Armory to finally receive your hard-earned Ray Gun Mk 2. Expert advice: Clear the area of zombies before initiating the scanning process to avoid interruptions.

    • Wraith Fire Upgrade (Mk 2-W)

    The Wraith Fire variant transforms your Ray Gun Mk 2 into an explosive powerhouse, ideal for clearing dense zombie hordes and dealing massive area damage. This upgrade path emphasizes aggressive playstyles and crowd control capabilities.

  • Direct your Ray Gun Mk 2 at the distinctive blue crystalline formations within the Conservatory to shatter them and collect the resulting Empty Canister. Strategic note: These rocks respawn periodically, allowing multiple attempts if needed.
  • Carry the Empty Canister to the specialized device located at Shem’s Henge (conveniently positioned near Speed Cola), which triggers the appearance of a formidable Abomination enemy. Preparation tip: Ensure you have adequate ammunition and defensive positioning before activation.
  • Allow the Abomination to energize three smaller blue rocks until they levitate, then survive the subsequent lockdown sequence by eliminating the swarming vermin. Advanced tactic: Use explosive weapons or area-effect abilities to manage the vermin efficiently during this phase.
  • Retrieve the transformed Explosive Canister and proceed to the Supply Depot to craft your newly enhanced Ray Gun Mk 2-W. The resulting weapon features significantly increased splash damage and unique visual effects.

    • Plague Variant Upgrade (Mk 2-R)

    The Plague variant introduces toxic damage-over-time effects, making it exceptionally effective against high-health targets and providing sustained area denial capabilities. This upgrade excels in defensive scenarios and boss encounters.

  • Secure an Empty Canister using the same method as the Wraith Fire upgrade process. Efficiency tip: Consider obtaining multiple canisters simultaneously if planning multiple upgrades.
  • Deploy an LT-53 Kazimir grenade through the Rear Patio window (adjacent to Double Tap Root Beer) to access the plant seed collection phase. Important reminder: Kazimir grenades can be purchased from the Mystery Box or specific wall buys.
  • Collect all four Plant Seeds by precisely targeting them with your base Ray Gun Mk 2 at these strategic locations:
    • Shem’s Henge – Check around the ritual site perimeter
    • West Balcony tree – Examine the elevated platform carefully
    • Mansion entrance left side – Scout the architectural details
    • Garden Pond staircase – Inspect the surrounding foliage
  • Insert your Canister into the designated slot within the Conservatory and systematically plant the collected seeds in the awaiting planters. Organization strategy: Plant in a sequence that allows efficient defense positioning.
  • Defend the developing planters against zombie attacks until they reach maturity, which converts the Empty Canister into the potent Toxic Canister. Defense tip: Deploy traps or use area-denial weapons to protect multiple planters simultaneously.
  • Transport the Toxic Canister to the specialized Garden Pond workbench to finalize crafting the Ray Gun Mk 2-R, which delivers corrosive projectiles that continue damaging enemies after initial impact.

    • Phantom Variant Upgrade (Mk 2-P)

    The Phantom variant offers spectral penetration capabilities, allowing projectiles to pass through multiple targets and obstacles. This makes it exceptionally valuable for corridor defense and dealing with shielded enemies.

  • Locate the Essence Bomb within breakable wooden boxes scattered throughout the map. Exploration tip: Systematic room clearing ensures you don’t overlook these containers.
  • Deploy the Essence Bomb on the rubble pile beside the Level 3 Armor station in the Service Tunnel to unveil a previously inaccessible chamber. Strategic consideration: Complete this step during lower-round transitions to minimize pressure.
  • Acquire two Refractors from the Conservatory’s fountain and the South West Balcony’s water feature. These items serve as navigation tools toward the hidden Doppelghast statues. Important note: Refractors emit visible beams when held.
  • Follow the Refractor guidance beams to locate three concealed Doppelghast statues, which must be activated and their spectral guardians defeated. Combat advice: Use high-damage weapons with fast reload speeds for these engagements.
  • Eliminate the summoned Doppelghasts to claim your reward Canister, then proceed to Eddie’s Bedroom to craft the ultimate Ray Gun Mk 2-P. This final variant features ethereal ammunition that bypasses conventional cover and delivers consistent multi-target damage.

    • Advanced Strategies and Optimization

    Maximize your efficiency by preparing appropriate loadouts before attempting the Ray Gun Mk 2 quest. Recommended perks include Speed Cola for faster interactions, Juggernog for survivability during defense sequences, and Quick Revive for solo players. Weapon selection should prioritize high-mobility options for navigation and reliable backup damage sources.

    Avoid common pitfalls by mastering map navigation before attempting the quest. Many players fail due to unfamiliarity with location names—practice moving between the East Foyer, Nursery, and Conservatory until the routes become second nature. Additionally, always clear zombies from critical interaction areas before initiating multi-step processes to prevent interruptions.

    Team coordination dramatically improves success rates for upgrade quests. Designate specific roles: one player focuses on objective completion while others provide crowd control and defense. For the Plague variant defense phase, position team members to cover different planter locations simultaneously. Communication about enemy spawns and resource status prevents overwhelmed situations.

    Advanced optimization involves timing your upgrade attempts during round transitions rather than mid-round combat. The quiet periods between waves provide valuable windows for completing complex steps without zombie interference. Additionally, consider which upgrade variant best complements your team composition and current objectives—Wraith Fire for horde clearance, Plague for boss damage, or Phantom for tactical penetration needs.
