I took the dive and picked up an original Splatterhouse PCB! Being born 1980 means the first time I saw this game in the arcade I would have been 7-8 years old, and boy, did it leave a long-lasting impression. I think I was both too intimidated to play it at that age, plus it was one of the more expensive machines, and my income is was whatever loose change my parents had.
After reading this wonderful interview
I spent a bit of time in the sound test menu, listening GWAAA's! and GYAAA's! that embarrassed them to do at the time. There's a lot of Hammer-horror-esque organ too... such a horror movie love-letter of a game.
Plus there was a 3D test option in the settings, which was a thing I forgot this game had. I never saw a 3D Splatterhouse cab in the wild, and it must have been pretty rare. In retrospect it kind of fell under the radar - it certainly didn't get the attention Mortal Kombat got - so I can kinda understand why it would just be chucked in a regular cab.
I won't bang on about the game - it's Splatterhouse! It's a very arcade-y arcade game, great for short bursts of gaming goodness. A real B-movie level, 1980's, video-nasty-type game!
