About this game
LOST ALTR is a casual solo card game set within the crumbling halls of a forgotten temple. You’ll face a series of Trials—mysterious encounters drawn from an ever-shifting deck. Each completed Trial leads you deeper into the Ruins of ALTR. Use Aspect cards to shape your fate—mysterious forces that grant you powerful advantages, but always at a cost. Built on the foundation of the Scoundrel card mechanics by Zach Gage and Kurt Biegand, a heavily reimagined experience, LOST ALTR blends strategy, luck, and lore in a dark, esoteric world. The path forward is never the same. The further you go, the more the ruins remember. What's Included Hierophant Journey (Standard Rules and Aspect Cards) 30 Aspect Cards to Collect through various Floors (Available in Journey Only) Neophyte (Single Trial with reduced cards and no Aspect Cards) Adeptus (Single Trial with Standard Rules and no Aspect Cards)
