Many know of the brilliant first-person shooter Duke Nukem 3D, which was packed with raunchy content, oodles of aliens to gib and massacre with an array of deadly weapons, maze-like missions and plenty of cheesy one-liners. Blood, on the other hand, is a lesser-known gem from the late nineties. Instead of sci-fi themes and nudity, there were horror tropes and extreme levels of gore, with enough dark humour to put a sadistic smile on any nasty player. Back in the day, Sunstorm Interactive crafted together two great Duke 3D expansion packs, and even stepped in to cook up the Cryptic Passage add-on for Monolith Studios’ cult-classic shooter.
