In the Call Of Duty Zombies map Shattered Veil, the Ray Gun Mark I can now be upgraded into three deadly Ray Gun Mark II variants: the Mark II W, Mark II R, and Mark II P. Each one has its unique upgrade process, and unlocking all three forms adds serious firepower to your loadout. Whether you’re hunting for high rounds or finishing the map’s Easter egg, knowing how to get each Ray Gun upgrade is key to survival.

Here’s a step-by-step breakdown of how to get each Mark II Ray Gun and upgrade it, starting with how to get the Ray Gun Mark I for free every game.

How to get a free Ray Gun Mark I in Shattered Veil

Instead of relying on the mystery box, you can unlock a free Ray Gun Mark I through an in-game quest:

  1. Unlock Pack-a-Punch by following the orange waypoint markers.
  2. Retrieve a fuse from a maintenance zombie located in the library.
  3. Follow the next waypoint to Ren’s computer in the director’s quarters. Shoot the computer and collect the circuit board that drops.
  4. Head to the elevator repair area and interact from the back. After surviving the horde, take the zipline to Sam in the mainframe center.
  5. Head upstairs and enter the service tunnels. Start killing zombies here and a lab technician zombie will eventually spawn (usually around round 10). He drops a floppy disk.
  6. Insert the floppy disk into a fax machine in the east foyer, near the T-Rex skeleton. After dealing with spawning vermin, a project Janus paper will print with a four-letter code.
  7. Take this word (e.g. “CRAB”) to the nursery chalkboard and translate each letter into a number based on letter groupings on the board.
  8. Head to the **service tunnels and enter the code into the keypad near the glass room. Defeat the *Doppel Gast*, grab his *severed arm*, and place it in the *armory* beside the Ray Gun Mark I.

This unlocks the free Ray Gun Mark II base version for every game.

Ray Gun Mark II W upgrade guide

This is the blue explosive variant of the Ray Gun Mark II.

  1. Shoot one of the blue glowing rocks found in:
  • Service Tunnel
  • Conservatory
  • East Foyer
  • Southwest Balcony
    This drops an empty canister.
  1. Take the canister to Shem’s Henge near spawn (looks like Stonehenge). Insert it into the device.
  2. Two Abominations will spawn. Wait for them to shoot beams at three small rocks on the outer edge of the Henge. When rocks turn blue, get them to charge into them.
  3. Once all three rocks are floating, a lockdown sequence begins. Defend from vermin, parasites, and zombies until it hits 100%.
  4. Collect the charged canister, then take it to the Supply Depot workbench to craft the Ray Gun Mark II W.

Ray Gun Mark II R upgrade guide

This is the toxic/poison green variant of the Ray Gun.

  1. Acquire a Kazmir grenade by crafting it or finding one in the service tunnel zombie hand.
  2. Go to double tap on the rear patio, and throw the grenade at the window below the machine. This pulls out a canister you can grab.
  3. Locate four orange plants outside the mansion and destroy them using:
  • Ray Gun Mark I
  • Explosives or Molotovs
    Plant locations:
  • Shem’s Henge
  • Left mansion entrance
  • Garden Pond near the trap
  • West Balcony by a tree
  1. Take the seeds to the Conservatory planters, plant all four.
  2. Go to the top of the Conservatory stairs and insert the canister into the charging station.
  3. Defend each planter from purple-eyed zombies for about 1–2 minutes. Once all are defended, the canister becomes toxic.
  4. Bring the canister to the spawn area workbench to craft the Ray Gun Mark II R.

Ray Gun Mark II P upgrade guide

This is the laser-light variant of the Ray Gun Mark II.

  1. Grab a Tomahawk by crafting it or picking one up at:
  • Tree stump near spawn
  • Nursery beside the child’s bed
  • Security Overlook near Pack-a-Punch
  1. Go to the service tunnel and look for the gas valves.
  • First, look for sparking gas from the leftmost pipe.
  • Throw a Tomahawk at the middle valve and then the “B” labeled pipe.
  • This activates a voice line, confirming success.
  1. In the mainframe chamber, check for a test tube filling with gas.
  2. Use any explosive to shatter the glass, revealing the canister.
  3. Search around the map for project Janus boxes and break them to find the Essence Bomb.
  4. Take the Essence Bomb to the level 3 armor wallbuy in the service tunnel. Interact with the rubble to unlock a secret room.
  5. Find two refractors in fountains at:
  • Conservatory
  • Southwest Balcony
  1. Place both refractors on posts in the secret room.
  2. Insert the gas canister into the machine. Melee the crystal in the middle to start a laser puzzle.
  3. Use the lasers and refractors to target and spawn Doppel Gast statues, and defeat all three:
    • Adjust the refractors using melee until beams reach new targets.
    • Final refractor placement will shoot light through ceiling gems to reach the third statue.
  4. After defeating the third Doppel Gast, the serpent statue glows, and your canister turns into a light canister.
  5. Bring it to the director’s quarters and craft the Ray Gun Mark II P at the workbench.
