Kinder der Toten Easter Egg Walkthrough

Forge four elemental swords, wake the knight at the altar, and seal the rift in the courtyard before the eighth wave of Doppelganger zombies.

Walkthrough steps

Activate Power
Restore power in the chapel basement. Three breakers, all on the north walls. The third only flips after you’ve killed a zombie within two metres of it.
Find the Sword Hilt
A blacksmith’s anvil in the courtyard. Drop a Sword Hilt charge near it. The hilt appears after one full round of melee‑only kills.
Forge the Elemental Blade
Carry the hilt through the elemental shrine matching your chosen path — Solais (light), Stachel (fire), Krause (lightning), or Ull (frost). Each shrine requires a different kill condition.
Awaken the Knight
Place your forged sword in the altar in the great hall. The knight rises and walks the perimeter. Follow him; he opens doors no key opens.
Defeat the Doppelganger
A reflection of your character spawns in the keep. Same loadout, same perks, same health. Outlast it. Do not let it down you.
Seal the Rift
Hold the centre of the courtyard for ninety seconds. The knight defends the four cardinal points; you defend the centre. Kill nothing inside the seal radius or it resets.
