About the game
Grim Penance is an add-on for Warhammer 40,000: Inquisitor - Martyr. An Imperial void station has spotted a Chaos flotilla heading on a collision course. Their numbers look too small to be a genuine danger, yet the Inquisition takes no chances with Khorne's followers. NeocoreGames developed and published it in 2019.
