Our take on Infernal Radiation

The defining combat idea is bullet deflection during fast demon encounters, with 20 demons distinguished by different abilities and battle patterns.

What is Infernal Radiation?

On Halloween Island, engineers build a power plant that draws energy from reactors connected to Hell.

After an accident spreads infernal radiation, residents in affected areas become possessed, creating a need for an exorcist. The game combines arcade clicking with RPG elements, bullet deflection, and demon-smashing combat. Players can explore the island, choose the order of exorcisms, and receive help from rescued residents. Encounters feature simple gameplay and difficult opponents, including 20 demons with distinct abilities and battle patterns. Cooperation takes place on one screen, while reports of the possessed reveal the island’s dark history.
