Mewgenics Boss Guide

Mewgenics follows a unique structure when it comes to categorizing managers. In particular, you will find five main types of these monsters in this game:

  • General Threats: Each act has a number of creatures, such as Kittens, Flies, Cat Caller, etc., that you have to fight in different stages to progress.
  • Mini Bosses: These are slightly more difficult encounters, normally around four in the first zone, with fewer appearing as you advance to new arenas.
  • Final Bosses: Each chapter i Mewgenics has a couple of final bosses (usually one), so you can meet about seven to eight of them in an entire act.
  • House bosses: These invade your home on their own after you clear certain areas.
  • Special Managers: Certain events along the way allow you to fight these rare mobs.
