Haeresis

A roguelike deckbuilder

Haeresis is a PC roguelike deckbuilder inspired by the solo card game Scoundrel. You climb a dark, ruined cathedral, deliberately putting enemies into your deck as you make your way toward a doorway tied to a religious pilgrimage.

Enemies in your deck

The central twist is that enemies become cards in your deck. The game’s card-building premise comes from Scoundrel, but Haeresis frames the climb around adding foes to the deck rather than keeping them outside it.
