Infra Arcana is a Roguelike computer role-playing game set in the early 20th century. The goal is to explore the lair of a dreaded cult called The Church of Starry Wisdom. Buried deep beneath their hallowed grounds lies an artifact called The Shining Trapezohedron - a window to all secrets of the universe. Your ultimate goal is to unearth this artifact.
The theme and inspiration for this game comes mainly from the horror fiction writer H.P. Lovecraft. It's not a pure H. P. Lovecraft game though, as it also draws flavor from various B-horror movies, as well as the 1997 first-person shooter Blood.
As a Roguelike - the game adheres to the virtues of the genre, such as high replay value and challenging tactical game play.
