Platform: Dragon 32
A late title for the Dragon 32 now, with one which was apparently similar to Uridium on the Commodore 64. A Uridium clone on the Dragon 32? This I would love to see!
The game was announced in a Quickbeam catalogue in March 1987, and Simon Hardy suggests that the game was reportedly seen working at a 6809 event in 1988.
In the end, the game would disappear without a trace, and is reported to have never been completed due to the shrinking market at the time. Developer Dave Gibbons had decided around this point to move onto the new 16-bit platforms instead.
Hopefully Dave can be tracked down at some point to learn more about the title, and crucially see if anything has survived that could be recovered and shown. If you know anything more about this game, please do get in touch.
With thanks to Simon Hardy for highlighting and for the information.
