Doom was never officially released on the ZX Spectrum , nor was it released on any other system of that time. Doom was just way beyond in computer development, but now you can play it in very retro style, thanks to Digital Reality. This looks as if it was officially released on the ZX in all it's first person goodness, it's a damn fine Remake. But don't get too excited, as although you can play the game, it's just a Demo and you'll most likely need an emulator. If you can't get it to work, sit back and listen to the awesome chiptune that comes with this release!
