The Darkest Shore — World War II Zombies Easter Egg Guide

Flip the two power switches (one in the U-Boat Pens, one in the Artillery Bunker) to power the doors and the minecart system.

Grab the sawblade (Bunker 3, right of the MP-40) and the handle (Artillery Bunker — one of the bunk beds by the minecart switch, right of the armor station, or the table right of Faustblitz), and assemble at the U-Boat Pens workbench (2,500 Jolts) — it starts melee-only.

Charge a zombie with the Ripsaw like a bayonet (hold ADS + fire) to rip out a charged spine (it glows at the tip), attach it at the workbench and kill ~20 zombies to finish — it now fires ricocheting saw blades.

Activate the Artillery-Bunker minecart switch, then ride the three route pairs — Bunker 1↔Beach, Beach↔U-Boat Pens, U-Boat Pens↔Bunker 1 — and on each ride look to the side at the midpoint and grab the green Elektroschnalle battery. Insert all three in the machine down the slope from Kugelblitz in Bunker 3 to raise the Übersprengen lift.

Shoot down the hanging corpse's head with the Ranged Ripsaw and place it on the headless body chained to the freezer door; killing zombies there starts a lockdown — shut off the 3 gas valves while dodging fire.

Man the AA guns and down the Stuka dive-bombers to restore the objectives (also used to blast a cliff boulder that frees a statue).

Activate the green-lit console to spawn a friendly Bomber; escort it to the artillery bunker where it drops a battery, then charge the battery with nearby kills.

Minecart to the Beach and blow open the wall by the artillery shell to reach the circular door with three holes. Collect the three Son-of-Nerthus statues: the Cliff Son (shoot the marked cliff rock with the Overlook AA gun so the statue drops to the Beach), the Drowned Son (give a normal zombie's spine to the Monk Head and defend the friendly zombie to the water — it returns carrying the statue), and the Moss-rock Son (fire the ranged Ripsaw at the moss-covered rocks — 9 possible spots around the Beach, Bluffs and Bunker 3 — until one drops it). Insert all three in the Ancient Door.

For each of three enemies, rip its charged spine, drop it in the freezer basket, do its escort task, then hook the glowing head in a lockdown:

• Wüstling — escort the friendly Wüstling to deactivate perks in order: Kugelblitz → Faustblitz → Laufenblitz → Lebenblitz
• Meuchler — weaken a Meuchler in the sacrificial room for its spine, then hit the friendly Meuchler 3× in the fog (follow its screams)
• Pest — first blow open all 7 fuse boxes with grenades (3 in the U-Boat Pens, 1 above the Bunker 3 doorway, 3 around the Overlook / Artillery Bunker), then deliver the Pest spine and, at each of its 5 scripted stops, ricochet a Ripsaw blade off the called coil into it (blue by the M1927 → yellow by the minecart → blue above the Bluffs door → yellow above the M1941 → yellow by the power switch)

Collect the two radio parts — one in the upper Bunkers (by the corpse right of the Combat Shotgun), one in the Bluffs (shoot the dangling man's arm above the Bunker 3 doorway with the Ripsaw) — and assemble the radio on the Overlook table right of the Mystery Box. Two destroyer ships then attack one at a time: read angle and distance off the wall charts by the cannon, set elevation and angle, and fire to sink each.

Take the monk's head from the freezer, place all four anointed heads on the ceiling hooks and survive the lockdown — Barbarossa's Pommel spawns in the central statue's hand. It takes the lethal (grenade) slot, stuns nearby zombies for a few seconds when thrown and self-replenishes every ~15 seconds, so use it freely as a panic tool right up until you spend it on the radio throw that starts the boss.

Throw the Pommel at the built radio and all players interact to start (point of no return — buy armour and refill Ripsaw ammo first). Fight four Meistermeuchlers, each with a specialist ability — purple (buffs nearby zombies), green (blinding blast), red (stun) and yellow (ricocheting sawblade) — across four phases: (1) Beach in fog, one at a time; (2) U-Boat Pens, two at once; (3) Upper Bunkers / Artillery, three at once; (4) Beach, no fog, all four and now permanently killable. In phases 1-3 a boss only flees — keep firing until hitmarkers stop; only phase 4 lets you kill them for good.
