What Is Mewgenics? Core Gameplay Explained

Mewgenics is essentially two games in one:

  • The Home Layer: Manage your cat household, breed kittens, and optimize furniture. Comfort and Stimulation affect breeding outcomes.
  • The Adventure Layer: Send cats on tactical grid-based missions. Positioning, action points, and environmental effects all impact combat.

Think of it as Into the Breach meets The Sims, but with cats and chaos at the center.

Tactical Combat Layer

Mewgenics 2026 Beginner’s Guide

Combat is about more than hitting enemies—it’s about positioning, AP management, and class synergy.

  • Classes & Roles: Fighter, Mage, Tank, Hunter. Cleric & Thief unlock later via Butch.
  • Starter Team Tip: Use 2–3 cats early; XP is split among active cats, so fewer early cats level faster.
  • Environmental Strategy: Terrain and positioning matter; high-movement cats thrive on open maps, Tanks excel on chokepoints.

Pro Tip: XP isn’t shared with the bench—keep your early squad lean.

Genetics & Breeding Systems Explained

Breeding passes traits and mutations to offspring. Understanding dominant and recessive genes is key to avoiding wasted breeding cycles.

Mutation Tier List (The "Gene-ius" Picks)

Tier Mutation Why It's Meta
S Extra Limb +1 AP. Single most broken trait in the game.
S Prehensile Tail Dual-wield Trinkets. Doubles passive buffs like Life Regen for Tanks.
A Photosynthetic Fur Heals 5% HP in Light tiles. Essential for “Sunlight Mage” builds.
F Glass Bones -30% Physical Resistance. Fragile; avoid early combat.

House & Furniture Meta

Furniture affects Comfort and Stimulation, which influence breeding outcomes and recovery:

  • High Stimulation: Boosts chance for positive mutations (~25%), but raises stress events. Key: Radioactive Litterbox, Tink’s Sparking Coil.
  • High Comfort: Speeds recovery, reduces retirement age. Key: Velvet Cat-King Throne, Plush Rugs.

The "Butch" Unlock Guide (NPC Class Priority)

Class Unlock Requirement Role
Cleric Complete "The Alley" Only class that can reliably Cleanse Bleed/Poison.
Thief Complete "The Sewer" Fastest class; excels at loot farming.
Necromancer Complete "The Junkyard" Summoner: Uses Action Economy to overwhelm bosses.

Starter Meta & Early Game Strategy

  • Run 2–3 cats early to maximize XP gain
  • Focus on a Fighter/Mage/Tank core squad
  • Prioritize mutations aligned with early objectives
  • Save resources for furniture upgrades boosting Stimulation or Comfort

Advanced Tips: Class & Mutation Synergy

  • Extra AP + Fighter = repeatable tactical loops
  • Photosynthetic Fur + Mage light zones = self-sustaining cats
  • Thief mobility = optimal loot farming early on

Gene Loop: Adventure → Retire → Breed → Repeat

Social & Inclusivity Angle

Mewgenics includes non-binary and asexual cat mechanics, plus a playful “Gay-dar” mechanic, making it socially inclusive—a trending topic on Reddit and Discord.
