Zeta-Designs is a Zoo Tycoon 2 fansite that was originally founded in 2009 by Sophie and Ruben, two Zoo Tycoon 2 designers from the Netherlands. After working together on the well known expansion Obsessional Ocean, they continued working together under the name Zeta-Designs. Although most (released) projects are made by Sophie alone, Ruben also made a few downloads, including the coastal biome reskin. The last couple of years, Ruben is not active in the community anymore, which means all of the downloads released at Zeta-Designs are made by Sophie.
