Never did like office parties... Christmas eve, and the staff at Macrobiology Industries Limited were having the usual office party, with all the usual hi-jinx and tears, but something very unusual was happening in the biohazard containment fridge. The predicted pandemic had never occurred, and so the fridge was full of unused swine-flu vaccines, but that night it jostled for space with the secretary's cucumber sandwiches and the boss's - sorry, not his, a friends - Viagra supply, all stored there for safe keeping until the party really got started. But the disco lights overloaded the generator, the fuses blew, the fridge shut off, and the staff all went their separate ways home to sleep off the excesses. January 2nd, happy new year! The security guard, first on site that morning, was slowly working his way around the offices and labs, tripping the fuse boxes back to life. He shook his head, bemused by the broken hinges on the doors, but the smashed containment fridge, and mucus-like stains on the walls and floor scared him enough to grab his SHARPS pistol, as strange things moved just out of sight...

3D Monster Maze is a computer game developed from an idea by J.K.Greye and programmed by Malcolm Evans in 1981 for the Sinclair ZX81 platform with the 16 KB memory expansion. The game was initially released by J. K. Greye Software in early 1982 and re-released later the same year by Evans' own startup, New Generation Software. Rendered using low-resolution character block "graphics", it was one of the first 3D games for a home computer, and the first game incorporating typical elements of the genre that would later be termed survival horror. 3D Monster Maze puts the player in a maze with one exit and a hostile monster, the Tyrannosaurus rex. There, the player must traverse the maze, from the first-person perspective, and escape through the exit without being eaten.
