Pathologic is a weird oddball of a game. Originally released back in 2005, the its full modern remake is due for release later this year. If that’s too long a wait for you though, developer Ice-Pick Lodge have today released The Marble Nest: a free teaser game that offers a story set parallel to Pathologic.

Previously only available for backers of the Pathologic Kickstarter campaign, The Marble Nest clocks in at several hours long. It offers an introduction to the creepy, plague-ridden town that acts as the stage for Pathologic’s story. A playthrough will feature some, but not all, of the mechanics from the full game, which blends together elements of RPGs, adventure, and survival games.
