In StarCraft 2: Wings of Liberty, there was one secret mission that concentrated on Hybrids (Protoss/Zerg units). That mission was called Piercing the Shroud, and you can gain access by unlocking it from the Media Blitz mission. Piercing the Shroud concentrated on a floating platform called Castanar. It contained secret experiments to merge Protoss and Zerg units.
Although there were many official hybrids in the game (Hybrid Destroyer and Hybrid Reaver), there were other hybrids in water tanks being experimented on. The following is a listing of these hybrids.
