Cavern Duel

Cavern Duel is a two player maze game for RISC OS.

26th Feb 2011 - Version 1.271 made available. The following issues were addressed:

  • Correction of many bugs that were introduced into v1.25. My laptop's + and = keys didn't map in VirtualRPC, which was not helpful. Therefore, silly schoolboy errors got put in by accident. Apologies for the sloppy code! More details are in the helpfile.

32-bit conversion of the game is a long way off, due to work and family commitments, as well as a distinct lack of coherent information on how to do it. Any assistance on this matter would be appreciated.

Cavern Duel puts yourself and your opponent within a complex labryinth of cave tunnels. The objective is simple - to find and kill your opponent, before he or she does!

Game SnapshotThe game is played using a split screen, showing overhead views of yourself and your opponent roaming about the maze, collecting food, weaponry and armour. Collecting such items improves your chances when you finally engage in battle.

Your health and armour are indicated by vertical bars to the right of the play area. Your current weapon is shown above your health and armour indicators.

Some of the weapons you come across within the maze are better than others. Potion bottles are also in abundance. Some however, have undesirable effects, such as reducing your health, which won't be helpful after you've barely escaped with your life just moments before.


  • Two player split screen
  • Keyboard controls
  • Various kinds of weaponry
  • Good (or bad) potions to help (or hinder) you
  • Location map of your opponent
  • Several differently designed levels to choose from
  • In-game settings allow for easier or harder game
Game Menu Snapshot


The game certainly runs fine on RISC OS 3.5 to 4.39, but may be slow on RISC OS 2 machines. RISC OS 5 users will require Aemulor or Aemulor Pro in order to run it. Virtual Acorn users will be able to run the game as well on their Windows or Macintosh systems.

Create your own caves

A fully multi-tasking level editor is included, enabling you to create and edit your own levels! Some example files are included to start you off, along with full instructions.

Although the editor works under RISC OS 4.02, do ensure you are in a high-resolution screen mode, as the windows appear too high up on anything less. This is something I'll deal with as soon as I have the time.

Future Improvements

The game is rather dated now, but it's still worth a few hours good fun with your mates! I'm hoping to support it (sporadically) over the years. Here are some of the changes I have in mind, in no particular order of importance:

  • Using Dr Wimp for !CavernEd (this will take some time, but will result in a more easy to use editor for everyone)
  • Get the game running on all versions of RISC OS, particularly RISC OS 5 and 6.
  • Improve the graphics. Even with 256 colours, the game looks rather 8-bit.
  • Improve code. The game is written in Basic, which proves too much for older machines. Andy Southgate's Gamesuite is a likely candidate for improving the code.
  • Change layout/enlarge game graphics. Rather than top to bottom, position the players left to right, and double the height of the sprites.
