MidBoss is a video game about possessing your defeated enemies in order to become stronger. You play the weakest of the dungeon denizens, an imp with no ability other than possessing other creatures. Your goal is to defeat and possess increasingly stronger creatures, unlocking their abilities for yourself and becoming stronger as you go along, and eventually defeat and become the dungeon's ultimate endboss.

The game is currently in beta and only available on Windows, that means certain features are as of yet not implemented. We have however tried our best to give you a smooth, bugless experience. Support for Linux and OSX will be added in the near future.

A press kit is available at kitsunegames.com.

Planned Features


Initially MidBoss was developed over the course of three days for Ludum Dare #25, designed around the theme 'You Are the Villain'. People thought it was fun, and so afterwards it was cleaned up and developed further and released in March 2013.

The current version of MidBoss is a complete, from the ground up overhaul of the old game - MidBoss Classic (still available to download and play) with new graphics, better interface, more abilities, more information, and a generally massively improved experience.
