This RPG is set in a world loosely based on the Catholic idea of Hell. Classes include Priests and Laymen (Warriors, Archers, Thieves, Scholars), Necromancers, and Demons (Hellspawns and Imps).
From the inside cover:
"Inferno has tried to be what players want. It is an imminently malleable system, allowing for a wide variety of gaming styles. Hack-and-slash body count scenarios or long-running character motivated campaigns are possible. Inferno is written to stand alone and unaltered. The future holds supplements which will not change the game, but expand it. No new rules, no system redesign, no B.S."
