Here's a game I never played back in the day and only recently loaded it up when I purchased the original on tape in July 2013...

Poseidon - Planet Eleven is a rather smartly presented space platformer by the talented Ash & Dave who also produced a few other cool little platformers for Hi-Tec, and Kamikaze and Slicks for Codemasters. The game allows you to control an underworld researcher and scientist who has to travel through a vast labyrinth of underground caverns to locate eight crystals that will help stabilise the planet that is going up in flames! Travelling around the game is easy enough though the controls are a little quirky, but the graphics, sound and game play ensure that the game is well worth the asking price of £2.99 (or was it £3.99?).

All eight crystals are collected...

...and one by one are thrown into the fire...

...to cool down the planet...

...and save the day.

The End.

HOW WAS IT COMPLETED?: Brendan originally cheated his way through the game, but I've coded a crazy hack version of the game that allows you to press the Commodore Key and jump straight to the ending. Download the file from HERE, start the game and press the Commodore Key to see the correct ending.

SO WHAT HAPPENS?: Once you have collected all 8 crystals and found the correct point to which they are released, the following ending message appears: "PLANET CORE STABALIZED. CONGRATULATIONS."


  • Brendan: Had no idea what to do on this game, no forum topics, no manuals, no reviews - nothing! The trainer lets you start with all 8 crystals, so thought they must have something to do with it. I found a map on World of Spectrum and made my way to something at the bottom that looked interesting, lo and behold, you land on it and all the crystals are used to complete the game.

    For a game with a pretty cool title tune, the ending is disappointing, crappy message, no tune, nothing! 0.5/10.
  • Vinny: I love this game and really enjoyed creating a crazy hack that allows you to travel through all the game screens.

    As for the ending... I think it's worth 3/10 due to the little animated sequence of the crystals being thrown into the fire, along with the message. It does give a very small sense of achievement :)
  • Frank Gasking: It has a cool little sequence with the rocks or whatever they are going into the lava, and then a small message. Probably I'd say a 3/10.
  • Andrew Fisher: It's a game that shows all the hallmarks of the various Compunet demo-makers who turned to making games - highly polished but lacking the spark and variety to make it great. It's fun but limited. I like the ending animation and message, with an extra ending tune and maybe a bit more (the guy flying away from the planet perhaps) it would have been even better.
  • Gaz Spence: The game is sort of an update on Elidon and the action is similarly sparse. The ending brings closure but lacks any real verve or imagination.

FINAL SAY: A great game, but not so much of a great ending.

G.E. RATING: 3 / 10
