Black Ops 6 Terminus Main Easter Egg Guide: Beamsmasher Crafting, Valve Puzzle & Nathan Boss Fight

Treyarch has raised the bar for round-based survival, and this Black Ops 6 Terminus Main Easter Egg Guide details every required puzzle step, Beamsmasher crafting code, and tactical boss phase needed to conquer the island facility. Terminus stands as the most mechanically demanding Zombies map in modern Call of Duty history, featuring oceanic exploration, biolab genetic puzzles, and multi-stage aquatic encounters. Consequently, preparation and strict round management are mandatory before initiating the central easter egg sequence.

Terminus Easter Egg Prerequisites

  • Power & Pack-a-Punch: Activate all three AMP generators across Control Center, Bio-Lab, and Living Quarters.
  • DRI-11 Beamsmasher: Craft or obtain the wonder weapon from the Mystery Box before round 15.
  • Tactical Loadout: Equip Aether Shroud or Healing Aura alongside Melee Macchiato and Jugger-Nog perks.

Black Ops 6 Terminus Main Easter Egg Guide: Beamsmasher Crafting Codes

Constructing the DRI-11 Beamsmasher wonder weapon requires solving the Bio-Lab calibration terminal and collecting three research components across the archipelago. First, players must defeat the armored Amalgam mini-boss that spawns near the Sea Cave elevator to acquire the Battery pack. Once retrieved, insert the battery into the charging dock inside the Bio-Lab and charge it using dead zombies.

Furthermore, players must access Peck’s research computer in the Bio-Lab office. The screen displays three elemental formulas (X, Y, and Z) that directly correspond to whiteboards scattered across the facility. Specifically, note the tally marks in the Living Quarters, Engineering room, and Mess Hall. Inputting the calculated coordinates into the terminal initiates the magnetic stabilization array, allowing you to craft the Beamsmasher without spending salvage.

2. Wonder Weapon DRI-11 Beamsmasher Bio-Lab Workbench Solve whiteboard math codes

4. Final Confrontation Tier III Pack Weapons Offshore Platform Defeat Patient 13 leviathan

Nathan Boss Fight & Patient 13 Leviathan Encounter

The mid-game climax occurs inside the Bio-Lab containment chamber, where players face Nathan, a mutated aquatic human experiment. During this encounter, avoid staying in open water corridors because Nathan utilizes devastating shockwave lunges. Use the Beamsmasher’s primary beam to stun him, then switch to high-DPS weapons like the Marine SP or Akimbo GS45 pistols to burst down his exposed bio-sac armor.

Subsequently, the grand finale transports your squad to the offshore drilling rig for the Patient 13 encounter. The colossal leviathan attacks with sweeping tentacle slams and acid rain barrages. Therefore, designate one teammate on anti-zombie crowd control while remaining players focus fire on the glowing orange pustules on Patient 13’s head. Successfully breaking all three pustule phases triggers the extraction sequence and awards the Terminus Dark Ops calling card.

Solo Player Pro Tips

If completing Terminus solo, purchase Self-Revive kits immediately from the crafting table. Equip the Aether Shroud Field Upgrade at Tier V to grant 5 seconds of total invulnerability during the tight Bio-Lab terminal alignment step.
