What the HELL is an action rogue-lite game where you battle demons in different hell-themed levels and destroy bosses. In each mission, you'll choose unique active abilities and create your own distinct skill set, utilize interactive environmental objects, develop your characters, complete various tasks, and show the hellish overlords who's boss!

The story takes place in a modern world dominated by powerful and influential demon lords in world politics, where humanity has access to dark demonic powers and resources but pays a terrible price for it.

A team decided to put an end to the hidden plans of the demon lords. They formed a special team composed of carefully selected highly trained soldiers and scientists from all over the world, and they officially declared war on hell. You step into the shoes of an angry commander assigned to venture through the depths of hell, fighting your way forward.
