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.

In MidBoss you play a weak monster in a dungeon: an imp. The imp is not noteworthy at all, beaten by simple skeletons or zombies, except that it has the ability to possess other creatures after it kills them. To progress through the game you level up and put points into four meta attributes (Violence, Cruelty, Relentlessness and Adamancy) which govern your playstyle. How these attributes come to expression in the core attributes (actually used to determine gameplay effects) varies depending on the multipliers of your current form. By unlocking new forms you gain access to their improved multipliers, and as you level those forms up you can unlock new abilities.
