Bubbler Amstrad CPC

For many years the ancient city of IRKON has been ruled over by the great and evil wizard VADRA. The inhabitants of IRKON have been suppressed and enslaved by this wizard and anyone who speaks out against him is instantly imprisioned, or worse. You are one of those citizens having been imprisoned long ago. As well as imprisoning you, as further punishment VADRA also turned you into a amorphous blob, without movement or form.

To help him keep control of the people of IRKON, VADRA forced the craftsmen to make vast bottles over which he cast an evil spell. The spell caused the bottles to ooze out large embryonic bubbles which burst leaving spellbound mutant creatures under the control of VADRA. When the people saw the first of these mighty bottles the called it: BUBBLER. — Cassette cover

Bubbler is a ZX Spectrum video game developed and published by Ultimate Play The Game in 1987. Although it uses isometric projection, as with Ultimate's second-generation isometric releases such as Nightshade and Gunfright, Bubbler used a scrolling display rather than the flip-screen of earlier titles such as Knight Lore and Alien 8.

As with the contemporary Ultimate title Martianoids, Bubbler was not written by the partnership of Tim Stamper and Chris Stamper. It was instead programmed by a team at U.S. Gold, and was therefore an Ultimate game in name only. It was Ultimate's final title for 8-bit home computers.
