Blood Altar (MAP25 E3M5) [Doom & Retro FPS Mods] Amalgoom is a megawad which intends to unite maps from Doom and Doom 2 using the Boom (complevel 9) format. The project is a homage to the original games and its creators. Main guideline was to study the original maps and the style of their respective authors, then to combine the two maps into one as if the original mappers had today's tools and time. This same principle was applied to the OST. Gameplay by AshtralFiend #Doom #DoomWADs #Modding #Re
