HOTFIX 1.1 — Inverted Probability Nerf

HOTFIX 1.1

A quick balance pass following UPDATE #1: the Inverted hatch mutation probability was reduced to the currently reported 0.5%.

Balance change

  • Inverted Hatch Mutation probability reduced — the currently reported figure is 0.5% per hatch. Guides quoting higher pre-hotfix rates are outdated.

Context

The Inverted tag matters for fusion: it carries onto fusion results and is one half of the meta endgame builds alongside Voodoo (Doll Hen). See the Inverted guide.

UPDATE #1 — Inverted Mutation, Incubator, Colossal Egg & Chicken Boss

UPDATE #1

The first major content update: 0.5% Inverted Hatch Mutation, the Incubator, the Colossal Egg with Storm Colossus, the 5,000,000 HP Chicken Boss event, 5 new chickens, and EGGSCELLENT.

New mechanics

  • Inverted Hatch Mutation — any egg can hatch an Inverted variant at a reported 0.5% chance (nerfed in HOTFIX 1.1)
  • Incubator — store eggs, hatch over time, luck boost, upgrade levels
  • Encourage Chicken in Ring

New content

  • Colossal Egg (aka "Colossus Egg") — 5 normal chickens plus the secret Storm Colossus (~1%), whose exclusive Storm Call AOE clears whole arenas
  • Chicken Boss Event — a massive armored chicken, player-tested at 5,000,000 HP, dropping Colossal Eggs at damage milestones (~5M damage = 1 egg)
  • 5 new chickens (Talon Titan, Rumble Rooster, Shockwave Hen, Dudoo Squat, Bow Buck)

Codes

The EGGSCELLENT code released alongside this update — see the codes page.
