Bloom

BlooM is a total conversion for Doom that unites the universes of Doom and Blood in a shared world. The story unfolds ten years after the events of Doom II, when a failed experiment by Cabal Co. with portal technology leads to a fusion of past and present, Hell's demons and Cult followers, creating a new reality — the Void.

The mod offers a full-fledged new episode of 8 extensive levels plus one secret level, inspired by classic Doom and Blood maps. The locations feature large-scale architecture, expansive skyboxes, expressive art style and rich atmosphere, as well as numerous references and memorable scenes.

One of BlooM's key features is its expanded bestiary: over 30 original enemies from Doom and Blood, plus more than 50 hybrid monsters combining traits from both series. Players can face them by choosing one of two characters — Doomguy or Caleb, each with their own arsenal. The mod presents around 20 types of weapons, including classic guns from both games, dual-wielding capability, and additional experimental specimens.

The soundtrack deserves special mention, as it sets the pace of events and amplifies the sense of a massive, brutal, and chaotic conflict between two worlds.

Despite some rough edges and difficulty balancing at higher difficulty levels, BlooM stands out for its high level of polish and feels like a standalone game that offers one of the most ambitious and memorable crossovers in the Doom universe.
