This week I have been playing around a lot in Photoshop trying to figure out the digging system of Optera. I have come back to this area of the game play many times in the past year or so. I have cycled through a lot of different ideas but I believe one makes the most sense.
Without going into too much detail I am playing around with the idea of a grid based system of various soil mediums. This will hopefully give the player a lot of freedom to create many nest types.
The idea is very early in its design stage but I have thrown together an image to help me visualize the concept.
