If you haven't already, please read the general overview about the Infocomics first.
When Tom Snyder Productions built their prototype engine for the Infocomics, they created a number of example images in the sci-fi superhero genre to show the capabilities, though without any actual characters (save for their looks) and with no story to go along. After the mutual agreement to go for collaboration between them and Infocom, it seemed like a good idea to re-use these – to use a modern-day term – assets. Gamma Force was born.
