Late last year, Nightdive Studios released Blood: Refreshed Supply, its second remaster of Monolith Productions' brilliant FPS debut. For PC gamers with one Blood remaster already in their Steam library, the highlight of the package wasn't anything technical—it was the addition of the concluding part of one of Blood's best mods.
That mod is Marrow, a new campaign for Monolith's deviously difficult and ferociously violent shooter. It's sort of Blood's equivalent of John Romero's Sigil—a continuation of Blood's storyline that concluded with protagonist Caleb slaying his demonic former master Tchernobog. Like Sigil, Marrow restricts itself to Blood's original assets (weapons, enemies etc) to power the experience, focussing instead on using those assets to build large and complex new maps for the game.
