Ladies and gentlemen, presenting XOR! In the words of the original 1987 XOR advert:
There are no random events in XOR’s labyrinthine palace, and there is no premium on hand-eye coordination. You have all the time in the world to work out the precise nature of the hazards you encounter. Logical thinking, strategy, and tactical problem-solving are all part of the XOR experience.
Featuring ‘15 mind-bending mazes, super-smooth high-speed scrolling and high resolution graphics’, XOR for the SAM recaptures all the excitement - and frustration - of the original game. Unfortunately the Order of XOR is long gone, but the puzzles retain all of the intrigue from 25 years ago.
Happy quarter century to an extremely difficult game! Enjoy!
The game is written for the SAM Coupé. To play the game, firstly you’ll need to download the SAM image, and either a suitable emulator or the original computer.
