This title is a significant modification for the classic shooter, Doom II: Hell on Earth. Released on October 31, 2021, it is available on PC (Microsoft Windows), Linux, and Mac platforms. It represents a unique crossover event, merging the distinct universes, enemy types, weaponry, and environmental elements from both Doom II and Monolith Productions' Blood.

Story and Setting

Set a decade after the events of Doom II, the narrative unfolds on an Earth striving to recover from the demonic invasion. While governments attempt to rebuild, the shadowy Cabalco organization operates in the background, aiming to seize control of former UAC facilities. Their objective is to construct a portal generator, not only to recall their fallen forces but also to resurrect Tchernobog. During this process, an unforeseen anomaly occurs due to an equipment malfunction, creating a spacetime disturbance. This event fractures reality, merging the past from Blood with the present of Doom II into a fragmented dimension known as the Void. The resulting vortex pulls back Cabalco's army and the demons previously vanquished by Doomguy. Cabalco's attempts to control the Icon of Sin prove futile, leading to the "War of The Void." Faced with an uncontrollable demonic horde, Cabalco scientists engineer "Hybrids"—servile yet deadly creatures born from the fusion of Hellish demons and Cabal forces. In this new conflict, Doomguy finds an unexpected ally in Caleb, brought forth by the temporal fusion. Together, they must confront not only the demons and Cabalco acolytes but also Cabalco's ultimate creation: the Hybrids.

Core Gameplay and Unique Features

The primary appeal of this modification lies in its ambitious fusion of two iconic shooter universes. Players can expect to encounter and utilize a blended arsenal of weapons and face a diverse roster of enemies drawn from both Doom II and Blood. The gameplay mechanics are rooted in the fast-paced, arena-style combat characteristic of its parent game, but are significantly expanded by the inclusion of elements from the other source material. This creates a fresh experience for fans of either franchise, offering a novel challenge and a unique blend of familiar yet distinct combat scenarios.

It’s not merely a reskin or a collection of new levels; it actively combines the core components of its source games.
