As an entrepreneur with an endless thirst for knowledge, Finch, the owner of Finchteq - headed up a high-tech facility with the purpose of studying the crystals and their effects. Of course, he researched the possible industrial and military applications to expand his economic empire too. This area is a much more modern aesthetic to the preceding copper mine and caves, and contrasts heavily with both. Here, we also see the experimentation with "Finchalis," a yellow bulb flowered plant that occurs naturally in the area and shares a curative relationship with the crystal.
The narrative reveals Finch's intention was to infect humanity and use Finchalis as a "cure", monetising its properties, while keeping the working population subjugated and compliant with crystal. The player can also use the plant's curious properties to their advantage, giving them enhanced senses and eventually forming the basis of a powerful bio-bomb to take out the facility.
The use of yellow was deliberate; linked with many interactive elements, even in Rosales' helicopter! Yellow is the primary colour of the player's "Battlefield Intuition," a HUD overlay that highlights interactive surfaces the player can grab and use as cover, as well as highlighting climbing points and enemies through solid surfaces. As well as its more practical use, we used the colour yellow to symbolise spiritual redemption as much as a physical cure. Contrasted with this is purple - the colour of the crystal and used to signify danger and the enemy.
Special mention should go to the "Funicular" station sequence and the train itself. They're used as a stage for a vertigo-inducing moment as the player is forced to climb around the carriages with a drop of thousands of feet below should they fail - another reason to experience more VR games!
