In a not-so-distant but very dystopian future, the neon is bright, the streets rain-slick, and Swiss chocolate is delivered via nanoteleporter directly into your system. You can see this in a screenshot from Ruiner:
If you step into one of the fields that are clearly labeled with the Swiss cross (and even square like the Swiss flag), nanomites crawl into your nose to simulate the taste of delicious Swiss chocolate made with the freshest milk from the Alps, perhaps gathered by Heidi herself; although I hear she’s more into goats. Once you’ve had your taste, the mites enter your bloodstream where they construct sugar molecules to nourish your body. That also explains why setting foot on a Swiss flag heals you in this game.
For shame, Reikon Games, for shame.
