This entry is part of a series covering Mutation's unreleased games:

• Arcadia demo / Our-Type
• Vaporizer
• Outlander
• Beach-Head
• Beach-Head II
• Raid Over Moscow
• Man Machine
• Egg
• Flipover
• Orb-It
• City Limits
• Outlander II
• Vac-Suit Jack
• Fantastic Island

There is little detail about Vaporizer apart from a titlescreen and the intended genre of multi-scrolling space shooter.

My guess is that it may have had some similarity to the scrolling section of Psygnosis' AWESOME.
