Hell Deck is a dark roguelike tower defense and deck-building game where familiar tactical rules are replaced by a brutal predation system. The battlefield becomes a living ecosystem where demonic creatures devour each other, gain new properties, and evolve into more dangerous forms. You must use sacrifices, mutations, and limited space to survive the onslaught of celestial forces. Build your own predator chain Your units don't simply take up positions and attack approaching enemies. They can hunt each other, and proper placement allows you to initiate absorption chains and strengthen creatures within your army. By sacrificing some units for others, you can gradually transform ordinary demons into significantly more powerful creatures, changing your army's composition right on the fly. Each round requires careful management of space and available cards. The board is grid-bound, so even a single unit deployed can change the entire system's development. Monitor your hand, inventory, and creature placement, combine their abilities, and create chain reactions that will help your army overcome massive waves of enemies and sacred invaders.
