One of the final games released on Duke Nukem 3D's Build Engine, Blood was the pinnacle of pixellated shooters before they were replaced by polygons. It came out at an awkward time, shortly before ground-breakers like Goldeneye 007 and Half-Life completely redefined peoples' expectations of the genre. But neither of the aforementioned games lets you shoot off zombie heads and kick them around, watch blood dripping down a wall after you chose shotgunned a demonic monk against it, or generally cause so much carnage. The graphic design was murky in that unique way that polygonal games wouldn't be able to achieve for years to come, and there is something genuinely timeless about Blood's well-animated pixel art. Every murky corridor you went down would yield some gruesome surprise - a disembollewed torture victim here, a lunatic there, all of which was enhanced by a rich soundtrack and creative arsenal of weapons including aerosol cans, voodoo dolls and plasma-firing skulls.
