Long, long, long before DOOM and even long before the first dungeon crawlers in 2D, the basic gameplay of a FPV in 3-dimensional enclosed rooms captivated a whole generation of ZX81 owners.

We actually speak about Malcom Evans' 3D Monster Maze from 1981. 🧌

And long, long ... long before the Sinclair ZX81 (to be inaccurate a bit more than 3 years) Commodore sent the PET into the race. Still, no port of the game ever actually made it to the PET. 

That is about to change now! Dave Curran aka Tynemouth Software has noticed, that the character set of the PET is sufficiently similar to that of the ZX81. And since Paul Farrow reverse engineered the original, all the puzzle pieces were available.

The result is 3D Monster Maze for the PET. It is as impressive as the accompanying article is worth reading. Considering the cost of today's polygon accelerators, one can't help but wonder, whether gameplay is linearly related to the number of transistors. (Well, at least not for me).

Great reading material.
