Just perfectly for Halloween, the first demo of Bloom has been released. Bloom is a project that merges Doom with Blood (clearly BlooM takes its name from the fusion of the words BLOOD and DOOM). Bloom's lore fits into the universes of the games Doom and Blood, story is situated between a temporary space during Blood events and 10 years after Doom II events. There has already been spent a huge amount of work into the project and it looks very promising what has been done so far. Screenshots, features and videos can be found in the ZDoom dev-thread.
