Fruity is a proprietary programming language developed by Guava-Half for their internal use. It comes with a huge amount of predefined procedures and macros (“fruits”, organised in “baskets”) to expedite work and streamline development.
Guava-Half does not offer Fruity for sale or licensing.
A character may learn Fruity as a simple KNOW skill. If working on a Guava-Half product, a character gains a +1 modifier on Computer Use and Computer Subterfuge provided their ranks in Fruity are at least equal to their ranks in the used skills.
